Yes, as long as the mother has B in her blood type (either B or AB), the father can have O.
A
ab+ a+ b+
The father's blood type can be O, A, or B.

Yes, the child's blood type can be B if the father has o.
For a baby with AB blood type : both parents should be AB. or one is AB and the other is B. or one is A and the other is B.
Yes, it is possible for a child to have a different blood type than their father. A child inherits one blood type allele from each parent, so if the child receives a B allele from their mother and an A allele from their father, they can have blood type B.
According to this online calculator - Yes http://www.biology.arizona.edu/Human_Bio/problem_sets/blood_types/btcalcA_popup.html
Yes. Both A and B are "dominant" genes, so if the parents have the genotype AO and BO, then there's a 1/4 chance the child will have genotype OO.
No
Yes, even though the father is blood type O he could father an O child, A child, or B child.
Yes. If the father were BO+ and the mother were AO+, there is a 25% chance their child could be an O+.
