Abilities » Primal Turbo | Energy » Rapid Strike Energy | Trainers » Temple of Sinnoh
If Temple of Sinnoh is in play, can I use Archeops' "Primal Turbo" Ability to attach a Rapid Strike Energy from my deck to a non-Rapid Strike Pokemon?
Yes, you can use Primal Turbo to attach Rapid Strike Energy to a non-Rapid Strike Pokemon. Normally Rapid Strike Energy would be discarded immediately, but Temple of Sinnoh removes all effects of Special Energy attached to Pokemon, so Rapid Strike Energy would not be discarded. But if Temple of Sinnoh's effect goes away, then Rapid Strike Energy would be discarded.

Abilities » Emperor's Eyes | Abilities » Mischievous Lock
What happens if Klefki with "Mischievous Lock" and Empoleon V with "Emperor's Eyes" Ability somehow both become active at the same time, like at the start of the game?
If Abilities activate at the same time, the Abilities of the player whose turn it is activate first.

Abilities » Emperor's Eyes | Abilities » Mischievous Lock
If Empoleon V with "Emperor's Eyes" Ability is in the Active Spot and my opponent brings up a Klefki with "Mischievous Lock" into their Active Spot, whose abilities are turned off?
Since Emperor's Eyes was in effect before Klefki became active, it takes precedence and Mischievous Lock does not activate as long as Emperor's Eyes is in effect. The converse is also true, if Klefki were active first and Empoleon V is brought up, Emperor's Eyes would not activate.

Abilities » Crazy Code | Abilities » Primal Turbo | Energy » Spiral Energy
Can I use Porygon-Z's "Crazy Code" Ability or Archeops' "Primal Turbo" Ability to attach Spiral Energy to a Pokemon that isn't a Rapid Strike Pokemon?
Yes you can, but then it would get discarded immediately. However, if that Pokemon was Paralyzed, Spiral Energy would remove the Special Condition.

Attacks » Curse Spreading | Abilities » Tera
If my opponent has Arcanine ex or Gyarados ex on the Bench, will its "Tera" attribute prevent me from placing damage counters on it with Drifblim's "Curse Spreading" attack?
No, placing damage counters is different than dealing damage, so it won't be prevented.

Abilities » Adaptive Evolution | Trainers » Rare Candy
Can I use Rare Candy on a Scatterbug the first turn of the game or the turn that Scatterbug is played, since "Adaptive Evolution" says it can evolve in those cases?
No, you can't use Rare Candy to evolve in either of those conditions because the text on Rare Candy specifically prevents it.

Abilities » Frontier Road | Abilities » Neutralizing Gas
If I use Escape Rope and my opponent brings up Galarian Weezing with "Neutralizing Gas", if I bring up my Wyrdeer V with "Frontier Road" Ability would it get to use "Frontier Road" or not?
Neutralizing Gas would turn on before Wyrdeer V becomes active, so Wyrdeer V would not get to use its "Frontier Road" Ability.

Abilities » Shield Star
If I use Zamazenta VSTAR's "Shield Star" Ability, does it still reduce the damage by your opponent's attacks if Zamazenta VSTAR is removed from play (e.g. Path to the Peak) or if abilities are turned off (e.g. Aerodactyl VSTAR's "Ancient Star")?
The effect of this Ability remains if Zamazenta VSTAR is removed from play or if abilities are turned off.

If I have no cards in my hand, can I use Rotom VSTAR's "Conversion Star" Ability?

Trainers » Earthen Seal Stone | Abilities » Fighting Instinct | Meta-Rulings » Meta-Rulings
Any effect that alters the cost of a Pokemon's attacks is intended to alter the cost of ANY attack that Pokemon uses, not just the ones printed on the card. This means any attack that the Pokemon is given access to, such as Earthen Seal Stone's "Star Gravity" attack when attached as a tool, can be used at the altered cost when effects such as Galarian Zapdos V's "Fighting Instinct" Ability are in play. For example, Fighting Instinct says, "This Pokemon's attacks cost {C} less for each of your opponent's Pokemon V in play"; however a more accurate description would be, "Attacks that this Pokemon uses cost {C} less for each of your opponent's Pokemon V in play." This applies to effects that reduce or increase attack costs, and goes all the way back to the Black & White series thru current series.
