If my opponent put a Stage 1 Pokemon directly into play using Tatsugiri ex's "Cinnabar Lure" attack, and I use Paldean Tauros' "Spirited Tackle" attack while that Pokemon is Active, would it do 90 or 180 damage?
It does 180 damage. Although the Stage 1 Pokemon is not an "Evolved Pokemon" in this scenario, it is still considered an "Evolution Pokemon" (Stage 1) that meets the requirements for Spirited Tackle.

If I put a Skeledirge (Stage 2) directly into play using Tatsugiri ex's "Cinnabar Lure" attack and I also have a Victini with "Victory Cheer" Ability in play, will Skeledirge's attacks do 10 more damage?
Yes. Although Skeledirge is not an "Evolved Pokemon" in this scenario, it is still considered an "Evolution Pokemon" (Stage 2) that meets the requirements for Victory Cheer.

If Pikachu ex has full HP and a Lively Stadium is in play, and Roaring Moon ex uses its "Calamity Storm" attack and discards the stadium, will Pikachu ex's "Resolute Heart" Ability prevent it from being KO'd leaving it with 10 HP remaining?
No, it won't. Calamity Storm does 220 damage and that many damage counters are placed onto Pikachu ex, so it no longer has full HP at this point due to Lively Stadium and the "Full HP condition" is not met in order to trigger Resolute Heart; then the stadium is discarded, returning Pikachu ex's maximum HP to 200, and therefore Pikachu ex is KO'd. However, if Calamity Storm does 230 damage (for example, if Roaring Moon ex has a Vitality Band attached), Resolute Heart would work; the attack places 230 damage onto Pikachu ex, thus meeting the "Full HP condition" in order to trigger Resolute Heart; then the Stadium is discarded, and Pikachu ex survives with 10 HP remaining (190 damage on it).

If I use Tatsugiri ex's "Surprise Pump" attack against my opponent's Kecleon with "Expert Hider" Ability and they flip Heads, does it do 100 damage or no damage?
Surprise Pump will do 100 damage. The attack ignores the damage reduction because Expert Hider is an effect.

If my opponent flips heads for Shuppet's "Enveloping Shadow" attack, can I still play Antique Dome Fossil or Antique Helix Fossil since they say to "Play this card as if it were a 60-HP Basic {*} Pokemon"?
No you cannot, because it is still considered to be an Item Card while in your hand.
Say my opponent and I each have 1 prize card left, then I use an attack like Pumpkaboo's "Reckless Charge" that KO's my opponent's Active Pokemon but also KO's Pumpkaboo due to "Reckless Charge's" recoil effect. However, my opponent has only one benched Pokemon with 20HP left, while I only have Iron Valiant ex on my bench. Does our game go to a tiebreaker since we both have a Pokemon on the bench, or will I win the game since Iron Valiant ex would be promoted as Active and then "Tachyon Bits" will be activated resulting in the KO of my opponent's last Pokemon?
All effects have to finish resolving before the winner is determined, so you could activate Tachyon Bits to KO the opponent's last Pokemon. You would win the game as you have achieved two win conditions but your opponent has only achieved one.
If Roaring Moon ex's "Calamity Storm" attacks a Pokemon without a Rule Box and chooses to discard the Neutralization Zone stadium, is the damage neutralized before discarding the stadium, or does the damage happen after discarding the stadium?
The *choice* is made to discard the Stadium and damage is calculated, however Neutralization Zone stadium prevents that damage from being done. After that the Stadium is discarded.
