If I have 4 Togekiss with "Wonder Kiss" Ability in play when my opponent's Active Pokemon is Knocked Out, do I get to flip 4 times even though I can only take one extra prize, assuming one of the flips is heads?: No, you only get to flip once. "The effect of Wonder Kiss does not stack" means that you can only use the Ability once regardless of how many Togekiss are in play. The coin flip is part of using the Ability, so you can't "stack" the flips.

If I have Togekiss with "Wonder Kiss" Ability in play and my opponent's poisoned Active Pokemon only has 10 HP left, do I take an extra prize when it is KO'd during Pokemon Checkup if I flip Heads for "Wonder Kiss"? What if Togekiss is in play and my opponent's active Pokemon knocks itself out?: The KO can be during either player's turn or during Pokemon Checkup, and it doesn't have to be from an attack. Wonder Kiss only looks at your opponent's Active Pokemon.
