Q1: When I use this card's inherited effect to digivolve into Eosmon in my hand, can it digivolve regardless of its digivolution requirements?
No, this card's inherited effect does not allow ignoring digivolution requirements, so you can only digivolve into a card that meets the digivolution requirements.
