Q1: When I have no face-up security, this card's At the Start of Your Main Phase effect and the digivolved effect of "BT18-004 Prolomon" were triggered at the same time. In this case, can I put a card in my hand face down under security by the effect of "BT18-004 Prolomon" and then use this card's effect to make it Memory+1?

Yes, it is possible.
