dont know if i should mention the elemental toads which are now canon that you originally made.
Alright long list:
Gamariki is the first summoning listed whom is a B-rank summoning, which can use A-rank water techniques as well as B-rank illusions. And he can use Oil techniques. this makes him a very versatile summoning whom can counter almost all fire techniques as well as using his illusionary power to confuse his target. This is mainly the way he fights. He can use the technique called smack of love which is obviously an awesome technique.
Next toad is Gamatatsu, When mentioning that he is a capable toad warrior as well as Gamariki it means that they are well versed in hand to hand combat, while he can also use water techniques up to A-rank as well as oil techniques. his fighting style is mostly water based and close combat. he is a human sized toad which can move quickly around.
Gamachu it seems he does or cannot talk and he always wears armor. he is a more relaxed toad being a friend of jiraiya and is usually summoned for more comfortable situations. he is specialized in kenjutsu and samurai techniques both up to S-rank as well as Strong Fist taijutsu which makes him an extremely dangerous toad in close combat. When he is smaller than a normal human he can easily evade and use his abilities to great extent. like other toads he can use oil techniques as well.
Gamabunta is the might Toad Boss. He uses an enormous Tanto, which is basically a katana which is proportionate to his body size. With his sheer size he has great strength and can carry a large weight as well as fight equal sized summons with ease. using his pipe he smokes he can easily create a smoke screen

he has complete mastery of water techniques up to S-rank. Due to his massive size and strength he is immune to B-rank techniques yet even with his size it is seen that he can easily and quickly move around a battlefield with grace and precision.
Fukasaku and Shima are the two greatest toads of Myobokuzan. They both possess the ability to use Sage Mode as well as enter Sage Mode with a user to grant him immense strength and power for un unknown period of time. While being on the users shoulders they can assist in gathering natural energy, they can help locate and fight the enemy. Fukasaku is a great strategist and experienced fighter, same goes for Shima. Fukasaku himself can use Water and wind techniques up to S-rank, as well as both toads can use Frog Kata and natural energy. Shima on the other hand can use fire and wind up to S-rank. They are extremely powerful and well versed, having a special set of techniques they can use like their tongue slash, the Goemon or their legendary illusion which not even Pein could breach.
Gamaken is the same size as Gamabunta and Gamahiro. He is ungraceful yet when seen in combat this greatly contrasts to what he says by showing immense physical prowess. he wields a sasumata, a giant fork like weapon as well as a shield. He is a close combat expert with great strength and durability, while also immune to B-rank and below techniques. He can use taijutsu and kenjutsu.
Gamahiro a powerful summon same size as Gamabunta as well, he wields two large katanas which he can use with extreme precision. He is a close combat specialist having mastered Taijutsu and Kenjutsu with dual wielding, which he can use with excellence. due to his great power and physique he is immune to b-rank and below ninjutsu. He can also be summoned through food cart destroyer, or simply summoned to combat great opponents with his twin katanas.
Gamakichi is the same size as his dad, gamabunta now. like his father he is also extremely deadly with a katana in combat as well as having mastered fire and water to S-rank power. he has a trait unlike the great three toads, which is he can use senjutsu to infuse into his elemental techniques as well as his taijutsu giving him an extreme edge over his opponents, this makes him a formidable summon which can easily surprise his opponent. Considerable the stronger one, stronger than gamabunta, Gamahiro and Gamaken.
dont need to mention they can all use oil as well as i feel i explained their strength and therefore their weaknesses....
