Q1: When several of my other Digimon with "Royal Base" in their traits leave the Battle Area at the same time due to an effect, if I activate this card's All Your Turns effect, will all of those Digimon not leave?
Yes, all those Digimons will not leave. The All Turns effect of this card is an effect that does not choose a card, but affects the whole group.
Q2: There is a situation where this card, your "BT19-053 Queen Beamon", and other Digimons with "Royal Base" as their traits are in the Battle Area. When my opponent uses "BT5-110 All Delight" and several of my Digimon leave the Battle Area at the same time, I activate this card's Opponent's Turns effect to prevent the other Digimon of mine with "Royal Base" in its trait from leaving. What happens if I then activate the All Turns effect of "BT19-053 Queen Beamon"?
The All Your Turns effect of "BT19-053 Queen Beamon" puts all Digimon with "Royal Base" in its trait to security. In this situation, all of your Digimon with "Royal Base" in their traits will not be deleted by the All Your Turns effect of this card, but if you activate the All Your Turns effect of "BT19-053 Queen Beamon" after that, all of your Digimon with "Royal Base" in their traits that were under the effect of being deleted All of your Digimon with "Royal Base" can be placed in security.
