Number three is correct.

Ooh, you're so close with number four. I think you should continue to thinking further into your first variation. For example, can White do anything here?

As Shaddy pointed out, there's a slight move order error for five. But I think you basically had it if we assume you simply switch :b13:

:b13:

and

:b15:

.

Does anyone has an idea for problems #1 & #2?

Is this bad for W? It looks playable to me, bnut will depend on the nearby areas.

If B tries a variation for 5, it's trickier but B collapses.
