Okay, so as you may know You can summon snakes via a few methods: Usual summoning ritual, or seals plus smearing blood on a pre-made seal. This pre-made seal comes in the form of a tattoo or a summoning scroll; however you still need to form the seals/draw blood. It just means you don't need to place your hand flat against anything as some summons tend to require.
The following Canon bios automatically get access to the snake contract and are the only (so far) canon bios that will allow you to have them.

(Kuchiyose no Jutsu: Kyodalja) - Summoning Technique: Giant Snakes
Type: Supplementary
Rank: B
Range: Short
Chakra: 20
Damage: N/A
Description: The user will summon a generic Giant Snake whose size can vary from a 10 meter long snake to ones the size of a boss summon, rivaling 100 meters long. These snakes vary in appearance and size and serve only as basic warriors, having only the normal characteristics of snakes. Although they are quite simple snakes, they are very enduring and resistant and, when big enough (about 50 meters long) they can take up to B-Rank damage.
Note: requires snake contract.
Note: can only be summoned once
So you just have to specify the size of the snake you're summoning with this technique, note that they need to be larger than 50 meters long, in order to have a resistance to B-rank damage. They simply look like the giant snakes we saw in the Forest of Death during the Chuunin Exams.
(Kuchiyose no Jutsu: Sōtōja) - Summoning Technique: Dual Headed Snakes
Type: Supplementary
Rank: B
Range: Short
Chakra: 20
Damage: N/A
Description: The user summons a double-headed, snake to attack his enemies. The snake is not big but is very fast and dangerous. Its bite carries a B-Rank physical damage and its body is small and slippery. Its mass is somewhat larger than the user but not by much.
Note: Requires signing of the Snake Contract
Note: Can only be summoned once
I often confuse this with another snake summon xD This seems to be from the move Naruto Shippūden the Movie: The Will of Fire and summons a rather tough snake, that has two heads and a resistance to B-rank damage.
These are simple enough both are essentially generic snakes except for the second one has dual heads. Both are also resistant to B-Ranked dmg and below meaning A n above will disperse them.
With the giant snakes, they will only resist the B-rank damage if you specify them being 50 meters or larger, otherwise they will disperse at a lower damage.
(Kuchiyose no Jutsu: San Kashira Ebi) - Summoning Technique: Three Headed Snakes
Type: Supplementary
Rank: A
Range: Short
Chakra: 30
Damage: N/A
Description: The user will summon a generic, 70 meter long Three Headed Giant Snake. These snakes vary in appearance and size and serve only as basic warriors, having only the normal characteristics of snakes. Although they are quite simple snakes, they are very enduring and resistant and they can take up to B-Rank damage.
Note: requires snake contract.
Note: can only be summoned once
This is the snake we saw in the Crush the Leaf Plan, back during the end of the Chuunin exams. Basically, these are just a generic snake... with three heads and B-rank resistance due to their 70 metre size.
and since you are Sannin...
(Kuchiyose no Jutsu: Manda) - Summoning Technique: Manda
Type: Offensive/Defensive
Rank: F
Range: Short
Chakra: 50
Damage: N/A (-10 to user upon summoning)
Description: Manda is a gigantic, 100 meter long snake who serves as the "leader" of all snakes. Fierce and aggressive, Manda is a shrewd warrior. To summon Manda, the user takes a big gamble, as he can easily turn on its summoner if he so deems it. Not only that, but the sacrifice and the amount of chakra needed damages the user, making summoning Manda a forbidden act. Manda has some unique abilities. Extremely fast and strong, his tail acts as a sharp mace that he can fling at the enemies with ease, speed and tremendous power (capable of overcoming even A-Rank defenses). Manda is also capable of using his chakra for 2 unique techniques: he can borrow underground (even if its affected by up to A-Rank techniques), tunneling through the earth at enormous speed or shed his skin, using a sort of substitution technique, where he trades places with his shed skin. While underground, Manda can sense the vibrations through the earth and pinpoint the location of his enemy. While completely immune to techniques A-Rank and below, Manda can take one S-Rank attack and survive by shedding his skins afterwards, although this can only be done once.
Note: requires snake contract
Note: can only be summoned once
His shed skin ability is another jutsu that we will cover later on... note the restrictions and the chakra/damage cost to you.
These are pretty easy to understand manda requires more chakra and deals 10 damage to you upon summoning him. He also has two special abilities the first allows him dig through a rank and below terrain and the second allows him to shed his skin as a substitution but only once
Focusing on the Dual Headed Snake... it can use the following two jutsu:
(Jasenshi) Spinning Snake Thorn
Type: Offensive
Rank: C
Range: Short-Mid
Chakra: 15
Damage: 30
Description: A technique exclusive to (Kuchiyose no Jutsu: Sōtōja) Summoning Technique: Dual Headed Snakes in which they will release drill-like projectiles from their mouths at the target.
Note: Requires signing of the Snake contract
Note: Can only be used by (Kuchiyose no Jutsu: Sōtōja) Summoning Technique: Dual Headed Snakes
Just a projectile released from each of their mouths. They can release multiple, however the C-rank power is divided between however many you release. So one from each head, would become D-rank each in power.
(Dakōmō) Snake Steel Net
Type: Offensive
Rank: A
Range: Short-Mid
Chakra: 30
Damage: 60
Description: Once the user has used (Kuchiyose no Jutsu: Sōtōja) Summoning Technique: Dual Headed Snakes, snakes emerge from the summoned snakes mouths in order of two's and from those ones others are summoned through the mouths in a continuous order in an attempt to capture their target. As the snakes continue to multiply, they become smaller and smaller the farther they are from the epicentre of this technique.
Note: Requires signing of the Snake contract
Note: can only be used by (Kuchiyose no Jutsu: Sōtōja) Summoning Technique: Dual Headed Snakes
Each Snake-head releases two snakes from it's mouth, then those release two from their mouths and-so-on until there are so many, that is basically buries your target underneath a pile of interwoven snakes.
The first seems pretty trivial as most will easily counter this but the second can provide a great distraction allowing the summoner a chance to simultaneously attack the target from a different angle than the snakes.
(Senei Jashu) - Hidden Shadow Snake Hands
Type: Supplementary
Rank: C
Range: Short-Mid
Chakra:15
Damage: 30
Description: Senei Jashu is a Ninjutsu technique that manifests a snake, which extends from the sleeve. The ninja can extend these snakes to attack a target. Once extended the snake can bite into the target to hold and bind them.
Note: Must be able to summon snakes
We've seen Anko, Orochimaru and Mitsuki use this jutsu on several occasions; essentially a small-scale summoning that erupts from your sleeve.
(Senei Ta Jashu) - Multiple Hidden Shadow Snake Hands
Type: Supplementary
Rank: B
Range: Short-Mid
Chakra: 20
Damage: 40
Description: Senei Jashu is a Ninjutsu technique that manifests a torrent of snakes, which extend from the sleeve. The ninja can extend these snakes to attack a target. Once extended the snake can bite into the target to hold and bind them.
Note: Must be able to summon snakes
Like the previous, only this allows you to summon more from your sleeve, creating a more effective binding or even to grab multiple targets.
Yes, that is a fairly common method of using them.
(Kyodaija Kawarimi) Snake Body Replacement
Type: Supplementary
Rank: B
Range: Short-Mid
Chakra: 20
Damage: N/A
Description: Snake summons have the ability to shed their skin in a manner of body replacement technique which is used for the replacement technique while the snake hides underground. During the battle with gamabunta and katsuyu, Manda used this technique to evade from toad oil flame bomb; the skin was deceiving however it had a transparent opacity, which in between attack wasn't noticeable.
Note: can only be used by Snake summons
A substitution jutsu for snake summons.
(Hebi Kage Bushin) Snake Clone Technique
Type: Supplementary
Rank: B
Range: Short
Chakra: 20
Damage: N/A
Description: A jutsu develop for spying and gathering information which involves the user summoning a small snake from his sleeve. The user will then have the snake transform into a pure reflection of themselves. The user is able to know exactly what the clone is doing. The clone is only able to use basic snake ninjutsu and taijutsu up to B rank. The clone is linked to the user and is controlled at a distance through mental commands, unlike normal clones which can act independent from the user.
Note: Counts towards the users clone limit.
Note: Only one can be made at a time.
A close formed essentially by a snake using the transformation technique. You have full control and awareness of what your clone is doing/where it is. Note that it only is able to use Snake Ninjutsu as well as taijutsu up to B-rank, which is the rank of this clone.
(Hebi Risu no Jutsu) – Snake Explosion Technique
Type: Offensive
Rank: A
Range: Short-Mid
Chakra: 30
Damage: 60
Description: The user turns their hands into a number of huge snakes that hit the opponent upwards. Next, one snake grabs the opponent in its jaws and drags the opponent into the pile of snakes left below. The user then sends a pulse of chakra into the pile, detonating the snakes into a massive explosion.
Note: May only be used once per battle
You hands *appear* to turn into snakes, since really only Orochimaru's hands can do that... anyway, you summon snakes through your sleeves and use them to slam your opponent up into the air, before one snake bites hold and drags the target back into the pile of snakes below. You then pulse your chakra to cause the pile of snakes to explode.
Excellent, let's try and finish this while I still have my Orange. ^^ Sorry by the way.
(Jagei Jubaku) – Snake Authority Spell
Type: Offensive/ Supplementary
Rank: A
Range: Short-Mid
Chakra: 30
Damage: N/A
Description: The user extends Large snakes from their sleeves, which then coil around the target/s and then binds them. With the further addition of the users murderous intent they then can weaken their targets resolve and temporarily paralyze them in place.

This follows the rules of Killing Intent and as such, this jutsu will cost two move slots, if you intend to use the killing intent along side the snake.
(Mandara no jin) – Myriad Snake Net
Type: Offensive
Rank: A
Range: Mid
Chakra: 30
Damage: 60
Description: The user will release a torrent of serpents out their mouth. This wave will rise and rush towards the target and covering them while biting them and crushing them.
Note: Must be able to summon snakes
This is what we saw Orochimaru use against Naruto in early-ish shippuden. The part after Kabuto and Sasori were supposed to meet or something, my memory is kinda foggy about that time xD
Pretty straight forward, you release a massive torrent of snakes from your mouth, with the aim to overwhelm and smother your targets in snakes.
(Hebiātsu: Yōso no sukēru) - Snake Arts: Scales of the Elements
Type: Offensive/Supplementary
Rank: A
Range: Short
Chakra: 30 ( -5 per turn to the user)
Damage: N/A ( +15 damage to snake ninjutsu)
Description: The user will make the Tiger then Snake hand sign and gather an elemental chakra nature. When the user uses any snake ninjutsu, they infuse the elemental chakra into the snakes scales, giving them different properties and extra damage and strength against elemental ninjutsu. The snakes will then go by elemental rank difference in strength and weaknesses. This works on every snake used in snake ninjutsu like using these with multiple hidden snake hands all the snakes scales would change.
Fire - The scales on the snakes will be fiery red when infused with fire chakra. The scales give off fire, making it where if they bind an opponent, they burn the opponent causing 3rd degree burns. The snakes fangs can also give off fire giving them burning properties when they bite down into opponents burning them in the inside of the area where they bite down.
Water - The scales on the snake will be light blue and white when infused with water chakra. When they bind someone, they can have water form from their scales and have the water injected into the opponent, causing irregular breathing to an opponent. The snakes can also have the water form behind them extending their length by 5 feet.
Lightning - The scales on the snake will be black and yellow when infused with lightning chakra. The snakes scale will be constantly giving off electric sparks. When they wrap around opponents, they can all give off an electrical discharge at the same time, shocking the opponent to the point that they can become paralyzed. The snakes can also bite down and give off the discharge inside the opponent's bodies, causing more internal damage like organ failure.
Earth - The scales on the snake will be gray and hard as rocks when infused with earth chakra. The scales are as hard as rocks and allows the snakes to be able to do more blunt damage and cause broken bones and deflect ninja tools. When the snakes wrap around the opponent they can cause broken bones and internal damage.
Wind - The scales on the snake will be light green and have a constant windy breeze come out from their scales. The snakes can give off a sharp blast of wind that can cause deeps cuts on the opponent.
Note: Usable three times a match.
Note: Must know Snakes Summoning
Note: Can only use 1 element at a time and requires a 2 turn cool down between usage.
Note: Each use lasts for three turns.
Note: Once a scale has been changed to one element it can't be changed again.
Note: Courtesy of Korra
Note that this only works on Snake Ninjutsu techniques and not the actual summoned animals. For example, Myriad Snake Net is compatible as well as Steel Snake Net, used by the Dual Headed Snakes.
This would strengthen your Snake Ninjutsu, allowing them to go off Elemental weaknesses instead of them counting as simply ninjutsu. The five basic chakra natures are all that you are able to apply and the effects of doing such are included in the jutsu description.
Type: Defensive/Supplementary
Rank: S
Range: Short (Self)
Chakra: 40 (-5 per turn to the user)
Damage: N/A
Description: The user will channel their chakra throughout their entire body. By being able to summon Manda, the user will summon a layer of Manda's scales that covers their entire body, giving their body the strength of Manda's scales. The scales will be able to take up to A-rank jutsus and are able to take one S-rank jutsu, but the user will have to shed the scales off their skin to survive it. The user will be able to get rid of scales anytime they choose, but then won't be able to use this jutsu again for two turns.
Note: Last for 2 turns
Note: Only usable by Snake users
Note: Can't have Manda on the field at the same time
Note: Usable twice per a match with a two turn cool down
Defensive jutsu where you summon Manda's scales over your body. To tank an S-rank means you have to shed the scales completely, essentially having the scales take the damage from the jutsu you are defending from. Otherwise, they can take two A-ranks before they shed.
