Yes, you can. Your Leader's [Opponent's Turn] effect will have activated first, so you will have added 1 DON!! card, meaning you have 5 DON!! cards. Then, you will add 1 more DON!! card with this Character's [On Play] effect, so you will be able to draw 1 card.
No, you cannot. In this case, you must play this Character.
