Q1: 2 copies of this card are in the battle area. Can I activate the Main effect on both copies of this card and play or use 1 of the specified cards with the cost reduced by the total value?
No, you can't. You can't activate multiple effects that play or use a card at the same time.
Q2: If I activate this card's Main effect while a Digimon such as ST12-03 Solarmon with a "players can't reduce play costs" effect is in the battle area, can I activate this card's Main effect and play 1 of the specified cards?
You can activate the effect and play such a card, but its play cost won't be reduced.
Q3: If I activate this card's Main effect while a Digimon such as BT9-047 Pomumon with a "players can't play Digimon by effects" effect is in the battle area, can I activate this card's Main effect and play 1 of the specified cards?
You can activate the effect, but you can't use it to play such a card.
