If I use Forretress ex's "Exploding Energy" Ability, can I attach any of the Energy cards that I searched for to Forretress ex before it is knocked out?
Yes. They would then be discarded with the Forretress ex.

If I bring up Weavile with the "Assaulting Hunt" Ability after my opponent KO's my Active Pokemon, can I switch in 1 of their Benched Basic Pokemon to the Active Spot?
No, because Assaulting Hunt only works "during your turn"

If my opponent has Duraludon VMAX with the "Skyscraper" Ability in play, when I use Inteleon VMAX's "G-Max Spiral" attack and choose to return the only Special Energy card attached to Inteleon VMAX to my hand, does "Skyscraper" prevent the damage or not?
The choice to remove the Special Energy card is made first, but then damage is done and finally effects of the attack. So removing the Special Energy card is an effect that doesn't happen until damage has been done and therefore blocked by Skyscraper.
If I have Venusaur with the "Jungle Totem" Ability in play, and I use Typhlosion's "Blazing Energy" or Charizard's "Energy Burn" Ability while it has a Basic {G} Energy attached, how much {R} Energy would be provided?
A. Each Basic {G} Energy provides {R}{R} Energy. Even though the Energy type provided changes from {G} to {R}, the card name is still Basic {G} Energy, so Jungle Totem still works.
If I have a Honchkrow V with "Boss Pockets" Ability and 190 damage on it and three Emergency Jelly tool cards are attached, do all of the tool cards trigger at the same time or do they trigger sequentially?
They trigger in sequence, so the first Emergency Jelly would remove 120 damage and get discarded, but the second & third Emergency Jelly would not trigger since there is now more than 30 HP remaining and no more damage would be healed.
