1. How to perform it.
2. What tools (if any) are necessary.
3. Strengths/Weaknesses
4. A situation you could use it in.
5. How you can counter it.
1------------------------------------
1. I would throws some kunai with pouches attached onto the loop at the bottom of the handle and throw them at the opponent so that they rain onto them when the pouches explode as they come into contact, I then attach a single explosive note onto the end of a kunai and activate it by channeling raw chakra and throwing the kunai at the notes as the active one sets on fire and explodes as soon as it reaches the other notes showering around the enemy.
2. Explosive notes, pouches and kunai will be needed.
3. Stengths are that they are explosives and are powerful enough to kill someone. A weakness would be that it is easily seen and the explosive notes may be able to be blown away at first, because the user has to throw a final kunai, so it takes time for the jutsu to come into affect.
4. To move an opponent from their spot or to use it on trapped opponent using my Nara clan techniques.
5. Using a powerful enough wind jutsu to blow the notes away or by dodging using another technique, for example. Hurricane fist to shoot you into the air out of the shower of notes.
2------------------------------------
1. I then channel a little portion of the raw chakra through my body and make myself disappear in a cloud of smoke, within an instant I then reappear behind you in a cloud of smoke and tap you on the shoulder.
"Hey Ty-ty sensei!
"
2. None will be needed, except yourself xD
3. Strengths are that you can easily dodge an oncoming attack and then quickly counter it soon after if appearing behind the opponent. Also if your opponent is too strong for you, it's a great way to escape. There are not many weaknesses despite it being banned

I think sharingan and byakugan can keep up with it.
4. To quickly counter after an attack has been thrown at me, and to catch the enemy off guard straight away.
5. It would be very hard to counter as the user can reappear directly behind you, unless you have sharingan or if you're clever enough to state that you see them disappear instantly and first reaction would be to attack behind sending a back hand or punch behind myself for good measure.
3------------------------------------
1. I gather in some raw chakra and then create the ram hand seals, releasing the chakra into the air and it projects over towards the nearby forest and a voice that sounds very familiar, so familiar because it is my own saying
"Hey! dumbass! over here!"
2. None will be needed.
3. Strengths are that it can confuse and trick the opponent by making them attack the area of voice heard, though it's weakness is that you cannot be seen doing this and must hide before use.
4. When I have been concealed and cannot be seen by opponent, for example, I use a flash of light to blind the opponent for A couple of seconds and then use this technique to project the voice directly behind them, they would turn to go and attack aimlessly at the voice and I can place a precision attack to the back of their head.
5. A way to counter this jutsu would be to reveal the actual position of your opponent so they are obviously found out and cannot really use that to an advantage.
4------------------------------------
1. After making the hidden mist jutsu appear I would easily sneak up behind my enemy and break his neck with no second thought or by slitting their throats with kunai, maybe even use a sword or other lethal weapon, leaving no space for them to counter and just 100% ruin their day.
2. Maybe a weapon for dispatching the enemy
3. A strength is that this is an instant kill and can deal with enemies fast, weakness is that the user really should be concealed or they will get countered.
4. When i have created the mist jutsu or cannot be seen by my opponent anywhere, I would just quickly dispatch them for their carelessness.
5. A way to counter this would be to use a jutsu to blow away any mist they use, if they use it. Or to have your back covered and make sure you keep an eye on your opponent's whereabouts.
