As for typings, there are 7 main types, other than the Leader type. Attack, Defense, Healing, Trap, Gather, Steal, and Bomb. Each Type has their on skill sets and are actually quite varied.

The Leader Felyne is affected by the other Felynes in your main Team. The Team consists of 5 Felynes and the Leader. 2 or more Felynes of the same Type will give the Leader Felyne a Skill of that Type, up to 4 Skills if you use 5 of the same Type. You can even give the Leader Skills from multiple Types, but only from 2 different Types due to the 5 Felyne maximum. My typical setup is 2 Healing Felynes and 3 Trap Felynes.
