Yes they can.
No. The parent's possible blood types are BO and OO. If the child is AO something is incorrect. Neither parent has an A to pass along.
Yes, if the AB parent contributes a B allele, and the O parent contributes an O allele, then the child will be BO, and will have type B blood.

Yes.
Yes, it's possible but there are very slim chances. It depends heavily on the genotypes of both parents
The possibilities include B positive, B negative, O positive, O negative.
yes
absolutely. as long as one of the parents is positive, the child can be positive. and if one parent is A the other B, the child can be A, B, AB or O depending on the parents' other alleles. so the child can definitely be A or B positive, but also A negative, B negative, AB negative, AB positive, O positive or O negative.
