Q1: Can I process the part of the effect after "then" in this card's {Hand} Main effect without meeting the "by" condition?
No, you can't. If you don't pay 5 cost while you have a Digimon or Tamer with the CS trait, the part after "then" in this card's {Hand} Main effect can't place this card as the top security card.
Q2: Can I declare activation and process the part of the effect after "then" in this card's {Hand} Main effect even when I don't have a Digimon or Tamer with the CS trait?
No, you can't.
Q3: Do I delete the Digimon that was played by this card's Security effect at the end of the turn?
Yes, it's deleted upon the deletion timing.
Q4: What is the processing order for an effect that triggers at the end of the turn and the deletion of this card played by its Security effect?
The pending processing for the effect that triggers at the end of the turn and the deletion at the end of the turn are considered to be processing that triggers simultaneously. Therefore, the turn player can choose the processing order.
