Q1: Can I process the part of the effect after "then" in this card's On Play When Digivolving effect even if the "if" condition in the 1st process isn't met?
Yes, you can process it. Even if your opponent has more than 5 security cards, this card's On Play When Digivolving effect will trash their top security card.
