If I use Walrein's "Frigid Fangs" attack and on my opponent's turn they somehow move Walrein to the Bench, do they still need more than 2 Energy attached to their Pokemon to attack?
Yes. The effect resides on all of the opponent's Pokemon, not on Walrein, so moving Walrein to the Bench does not get rid of the effect.

If I Knock Out my opponent's Active Pokemon with Wo-Chien's "Entangling Whip" attack and take my last prize card but also discard the last cards in my deck, do I win or lose because I have no cards left in my deck?
You win. You lose if you can't draw a card at the start of your turn, but since you took your last prize the game ends before that happens.

If my opponent put a Stage 1 Pokemon directly into play using Tatsugiri ex's "Cinnabar Lure" attack, and I use Paldean Tauros' "Spirited Tackle" attack while that Pokemon is Active, would it do 90 or 180 damage?
It does 180 damage. Although the Stage 1 Pokemon is not an "Evolved Pokemon" in this scenario, it is still considered an "Evolution Pokemon" (Stage 1) that meets the requirements for Spirited Tackle.
