On point 2, I assume your talking about 3 and 5 in the room with Halsin? If that's the case I can confirm its possible to clear that room and free him without making the rest of the keep hostile. Either someone did escape, there's a wardrum somewhere in there (although I don't recall one), in conversation you asked Halsin to follow you (he actually suggests he doesn't immediately follow, saying doing so will likely make the whole keep hostile), you made them hostile in another way, or its a bug. But you CAN clear that (and most) rooms in the goblin camp provided your careful and destroy any wardrums, without triggering the rest of the goblins.
Apart from wardrums, someone escaping to alert others, and going with Halsin, the only way to alert the whole keep and camp that I'm aware of is to kill all three leaders.
