Yes, but 'had been' is also possible for 3. given that the second part of the sentence is in the past tense.
If she had been a princess (at that time), she would have married a King. But she wasn't/hadn't been, so she didn't.

Had she been a princess, she would have married a King.

Agree with you, Raymott. Now, I think 'had been' is better. I just went along with the answer suggested.

were - would
had been - would have
