Black hole inside a larger black hole.

Now, one of the stars might be a black hole in its own right.
Yes, but you must carefully consider that the standard meaning of the term "black hole" in the underlining theory is based on the existence of a global event horizon, which is not applicable to such inner body. So, some different kind of surface should be identified to describe it, which is not a trivial task (this is an active field of research in numerical relativity).
