Hey man, im not a pro or anything but ill try to help out (maybe wrong though)

A1: Fei & fang increase spark damage by 80%. Zegar increases spark damage by 50% but it says probable spark damage increase on the wiki. Im pretty sure these dont stack because they do the same thing. Use zegar's sbb first to get the crit buff and fei&fang to overwrite zegar's spark buff. Raaga/zenia (7star)s are better for spark than fei and fang. Rhoa puts a "debuff" on enemies for increasing spark damage and it will stack with other spark buff because rhoa puts it on the enemy and other spark buffing units puts it on your units.

A2: This one is tricky since they do the same thing kinda. Seria boost her own, as for leorone he boost everyone else's. I know that if seria uses her sbb whle leorone is already used, it wont override everyone else's. But it might override her own. But it also might stack since seria only boosts her own.

A3: Im not sure how much leorone increase stats by, I know that atro increases atk and def by 100%. depending on witchone you use second, it will overwrite because they do the same thing.

Conclusion: lets take minigation for example. Minigators usually boost def by 140% and using any other def up buff via percent will override because its in the same class of buff. but if you use melchio who increases def in accordance to atk, it will stack. hopefully this helps, good luck
