Haakon, Stromgald Scourge and Karador, Ghost Chieftain
1 and 2 are correct, but 3 is not. You can cast your non-Knight from your graveyard after having cast any number of Knights.
When you choose to cast something from your graveyard with both Haakon and Karador on the battlefield, you specify which of those effects is allowing you to cast it. If what you're casting is a Knight, you can use Haakon, and that won't affect your ability to use Karador to cast something that's not a Knight later in the turn.
