About the Special's animations, those heavily differ from character to chracter. Ike for example has SpecialHi1-4 and SpeciaiAirHi1-4 for grounded and aerial upB respectively.
Charging moves usaually have a start, loop and ending animations. Again in Ike's case it's SpecialNStart, SpecialNLoop, SpecialNStart and the same for aerial version just with Air before the N.
The pattern for attacks in general seems to be AttacktypeAirXState
Attacktype can either be Attack or Special and Air is just added if it's an aerial or an aerial version of a B move.
State is only used for charged moves. For smashes it's Start, Hold, End.
X can have a lot of different values.
