The blood type of any children would depend on the zygosity in the woman. (Both O and Rh negative are recessive, and will be homozygous in the man).
If the woman is homozygous B, then the children will B.
If the woman is heterozygous B, either O or B (with 50% chance of each).
In the same way, if the woman is homozygous Rh positive, then the children will also be positive. If the woman is heterozygous, then children will be either positive or negative.
In short, the possibilities for child blood types are either B or O, with Rh positive or negative.
An Rh negative man can marry an Rh positive woman. There is no reason this cannot happen.
Yes, an A positive man can marry an A negative woman. Blood type compatibility does not affect the ability to marry or have a successful relationship. It is only a concern during pregnancy if the mother is Rh negative and the father is Rh positive.
With proper precaution's, it is possible.
Yes
the child has o negative blood
There is a 50% that offspring will be Rh negative.
Certainly.
Yes, an O negative woman can marry an AB positive man. Blood type compatibility is not a factor that determines whether individuals can marry or not. It's important to understand that any potential blood type incompatibility would only be a concern during pregnancy and childbirth. Consulting with a healthcare provider would be beneficial to address any related concerns.
of course she can
There should be no problem concerning the blood groups. Only when the woman is Rhesus negative and the man is Rhesus positive, the offspring can be affected by Rh-disease (see: http://en.wikipedia.org/wiki/Rh_disease)

A woman with type O negative blood can marry someone of any blood type. An Rh negative woman will get an injection during each pregnancy to lower the risk of complications in future pregnancies.
