If I attack with Wormadam's "Matron's Anger" and I have 3 parts of a V-Union Pokemon in my discard pile, does that count as three Pokemon for adding to the attack damage?
Yes, in this case "Pokemon" in Matron's Anger's attack text means "Pokemon Cards".

Does Probopass' "Magnetic Pull" attack do 40 damage if the opponent cannot switch their Active Pokemon to the Bench or if the Bench is empty?
If you cannot switch the opponent's Pokemon there is no "new Active Pokemon" to be damaged, so no damage is done.

If I have an Alolan Raichu with Speed Energy attached or a Starmie with Wash Energy attached, if I use their "Electro Rain" or "Multishot Star" attacks and discard those Special Energy cards would it get through Duraludon VMAX's "Skyscraper" Ability or not?
Because you don't know how many targets to select until you discard all the Energy, the process is to discard the Energy first, then choose which Pokemon take damage, and then apply damage. Since for those particular attacks the discard happens first and THEN damage is applied, as long as there are no other Special Energy cards attached to Alolan Raichu or Starmie the damage would not be blocked by Skyscraper.
