For example parents with AB and O blood types can either have children with blood type A or blood type B.

Identical twins will always have the same blood type because they were created from the same fertilized egg fraternal twins can have different blood types again providing the parents do because they are created by two fertilized eggs. The Rh - factor is inherited separately from the ABO blood types. So yes it is possible for siblings to have different blood types.
