Can I play Plus Power or Electropower or Power Tablet on my first turn if I'm going first and am not allowed to attack?
Yes you can play those. Keep in mind there are some Pokemon (like Latios-EX with "Fast Raid" attack) that are allowed to attack on first turn.

The wording of PlusPower is now as follows, "During this turn, your Pokémon's attacks do 10 more damage to the Active Pokémon (before applying Weakness and Resistance)." This card no longer attaches to a Pokémon when used.

If you use a PlusPower on a attack that does 0 damage, will it do 10 damage? Like for example, Kangaskhan's Fetch will it do 10 damage with a PlusPower?
No, PlusPower will only add 10, *if* damage is done. Fetch doesn't do damage.

Can you [play] more than one PlusPower[?] 2, 3, 4?
Well you can have up to 4 in your deck, so if you had all 4 in your hand you could use them all at once yes.

Does a PlusPower work with Hitmonlee's Stretch Kick attack?
It does not. Pluspower only adds to the total if the attack does damage to the [Active] Pokémon only.
