Q1: Can I place just 1 card in digivolution cards for the conditions of this card's On Play When Digivolving When Attacking effect?
No, you can't. A "by" condition can't be met if only some of the required actions are performed. The conditions for this On Play When Digivolving When Attacking effect require you to place the specified number of cards as the bottom digivolution cards.
