The original Castle Island which spanned a longer period of time had:

Medieval, Flame, Metal, Platinum, Hot Metal, Wizard, Dark, DarkFire, White Knight, Black Knight

Ten dragons total. I'm guess is that for this event, the same dragons minus three will appear in this one. Pretty safe to say that White Knight and Black Knight will be the last two that you face.

Two through five are likely some combination of: Flame, Metal, Platinum, Hot Metal, Wizard, Dark, DarkFire.
