They call Hurt's character "The War Doctor", but as I recall he made the decision himself to not go by "Doctor" because of what he knew he had to do, so it's almost like he abdicated the title.

The metacrisis doctor was a kind of botched regeneration, which ended up half human (presumably on his mother's side), and thus doesn't count either.

Tennant's doctor in these three episodes is seen as a distinctly different doctor than 10, just "with the same face", so he counts as 14

We still don't know whether this bi-generation thing is stable at all. Maybe we won't see David Tennant as often as we think we will.

Jenny's case is unusual, as she was a clone of the Doctor, who the Doctor treated as his daughter. And you know the inside joke, that the actress who played Jenny (Georgia Moffett) was the real-life daughter of the actor who played the 5th Doctor. And the further meta-joke, which is that David Tennant eventually married the actress who played his clone/daughter.
