Well Issei will be staying with Rias at the Gremory Palace after they get married so probably the other girls will stay there too.

As to what kind of father Issei will be. Well all being said, i'll say he'll be one like Sirzechs. Playing with them everyday, gets punished by his wives for trying to teach them perverted things but i'll sayhe'll have a good relationship with his children.
