Q1: Can I use this card's End of Your Turn effect to grant "Quick Attack" to one of my Digimon and then not attack with that Digimon without rest?
No, it cannot. Digimon that are given "Quick Attack" by this effect will attack without rest as much as possible.
Q2: When attacking with this card's End of Your Turn effect, can I attack with a Digimon in Rest state?
Yes, you can attack with a Digimon in rest state.
Q3: I have two copies of this card in my Battle Area. At the End of Your Turn, I attacked with the first card's End of Your Turn effect. Can I attack with the second card's End of Your Turn effect after that?
No, you cannot attack with the effect of the second card. While attacking, you cannot declare a new attack. In this situation, at the end of your Turn, the two When End of Your Turn effects of this card are triggered simultaneously, and you attack with the first End of Your Turn effect. Before the Counter timing, the second When End of Your Turn effect can be activated, but since you cannot declare an Attack during the Attack, the second card cannot attack even if you activate it.
