И is Mario due to her being the main protagonist. Й is Luigi due to him being close with И. А, Д, Т, and ТӀ are Peach due to them being the rest of the captured letters. Л, Н, and П are the Toads due to them being part of the heroes. Ч is Yoshi due to her being the only letter to have magical powers. For those of you who don't know, Ч is based off Cirno from Touhou Project, meaning she has ice powers. ГӀ is OBVIOUSLY Bowser, no explanation needed. Bowser Jr., Kamek, and Bowser's minions don't have equivalents due to ГӀ being the only villain. М and О are Wario and Waluigi because they're the bullies. К, КӀ, and ОЬ are also bullies, but they don't have equivalents.
Nope.
