Sure, as long as they are fraternal twins and not identical twins.
Mom could be AO (or IAi) and Dad could be BO (or IBi) and parents could both be heterozygous for Rh factor. Other combinations of parents could also produce this result.

It depends if the mom & dad have A- and B+. If the parents each have the different blood types, and if the twins are fraternal, then there'll be a 25% chance of each twin getting the different blood type.
Remember that mom's blood do not transfer into her child during pregnancy. Both mother and child has separate blood vessels running in the umbilical cord.

Definitely it is possible that a mother can have twins with different blood groups if they are faternal influenced. i.e is the sperm divides into two and combines with the ovary of the female so that the twins have different blood groups and twins should not be identical twins

If the twins are not identical twins and they are fraternal twins, then it is definitely possible. This is because two completely different sperm fertilized two completely different eggs, also explaining why fraternal twins can be boy/girl. Identical twins result from a splitting of one zygote, the union of sperm and egg.

Sure, if they are fraternal. It is like having two different pregnancies.
However, I ain't sure about the + and- thing. I just spew forth my opinions.
