Possible. Tell the OB of the RH difference.

Yes. They're just genes - mix & match is normal.
The child will be A or B or AB, Rh+ or Rh- . So yes, the child can be A-.

I'm not sure how negative or positive is determined, but a B mother and O father can have a B child.
if your child is negative, i would ask for a blood sample from the mailman
No. They can have an O positive, an O negative, A B positive, or a B negative child.
