Q1: This Digimon digivolved by this card's When End of Your Turn effect and attacked with that Digimon. In this case, in which order can the When Digivolving effect and When Attacking effect of the Digimon be activated?
Since they are triggered simultaneously, the player can choose the order in which they are to be activated.
Q2: 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.
