If I use Sylveon's "Wink Wink" attack to have my opponent discard Ilima, can I use Victini's "Victory Star" Ability to force my opponent to re-flip their coins?
Yes, you can. If your opponent flips a coin as part of your Pokemon's attack, you can use "Victory Star" to force them to re-flip those coins; but keep in mind you will have to re-flip your coins for Ilima too.

If I use Sylveon's "Wink Wink" attack and discard my opponent's Diantha, can I get 2 cards from my discard pile even it 1 of my {Y} Pokemon was not Knocked Out on my Opponent's last turn?
No, you still have to meet the requirements of the card's text. You can discard the Diantha, though.

If I've already played a Supporter this turn and use Sylveon's "Wink Wink" attack, can I still use the effect of a Supporter I discard from my opponent's hand?
Yes. You are not playing a second supporter, but using its effect via an attack.
