Q1: Multiple effects trigger when this card attacks. In what order do they activate?
The effects trigger simultaneously, so the player can choose the activation order.
Q2: I have this card and EX8-065 Ryutaro Williams in the battle area. When this card attacks, I activate EX8-065 Ryutaro Williams's Your Turn effect and digivolve this Digimon into a card in the hand. Can I then activate this card's Raid or When Attacking effect?
No, you can't. If an effect is lost while it's pending activation, it can no longer be activated.
