On my last turn I attacked with Zebstrika's "Coordinated Bolt" attack. If Zebstrika gets KO'd or otherwise leaves play and on my next turn I use Zoroark's "Phantom Transformation" Ability to bring the Zebstrika back onto the Bench, can I use that Zebstrika's "Coordinated Bolt" attack with additional damage.
Yes, you can. Although Zebstrika left play and came back it is considered a different Pokemon on the previous turn.

Can Gutsy Pickaxe attach Single Strike Energy if one is revealed as the top card of my deck?
No, it cannot. Single Strike Energy doesn't count as a Fighting Energy while in the deck.

If I use Single Strike Style Mustard to put Duraludon VMAX directly onto my bench, can I later use Cheryl to remove damage counters from it despite it not having evolved into the VMAX?
Yes, it is still an "Evolution Pokemon" since it has an Evolution box printed on it. It would not be an "Evolved Pokemon" but that is not what Cheryl requires.

If Temple of Sinnoh is in play, does Meloetta's "Melodious Echo" attack still do 70 damage for each Fusion Strike Energy attached?
Yes. Temple of Sinnoh removes all effects and provides 1 Colorless energy, but it does not change the card name to be something other than "Fusion Strike Energy". So Melodious Echo still does 70 damage for each attached Fusion Strike Energy you have in play.

If Lunala uses its "Lunar Pain" attack on a Pokemon that already has two damage counters on it, does it place four more damage counters on that Pokemon for a total of six?
No, that's not now it works. Lunar Pain counts how many damage counters are already on the Pokemon and places the same number of additional damage counters on it. So in your example a Pokemon with two damage counters would now have a total of four on it, not six.

If I attach a Grass Energy to Skiploom with the "Solar Evolution" Ability but there are already 4 Jumpluff either in play or in the discard pile, can I still search my deck for that Pokemon and fail?
You cannot use Solar Evolution to search your deck since it is public knowledge that you won't find any Jumpluff if all four copies of the card are in known areas.

If I have a Kecleon with the "Chromashift" Ability in play and two basic Water Energy and a basic Fighting Energy attached, and my opponent has a Jolteon with the "Thunderous Awakening" Ability and a Memory Capsule attached, would Kecleon still be considered a Fighting type Pokemon?
No, it would not. Thunderous Awakening would turn off Kecleon's Chromashift Ability completely, therefore Kecleon would be a Colorless type.

If Temple of Sinnoh is in play, does Double Turbo Energy provide one energy or two.
It would only provide one {C} Energy and would not reduce the Attack damage.

If I play "Canceling Cologne" and then somehow switch out the opponent's Active Pokemon, does the new Active Pokemon have its Abilities or not?
The effect of Canceling Cologne is on the opponent's Active Pokemon position rather than on the Pokemon itself. So if the opponent's Active Pokemon changes after Canceling Cologne has been played, the new Active Pokemon would have its Ability removed and the previous Pokemon would have its Ability restored.
