Our house currently has multiple addresses because the utilities are divided into 8 or so separate suites almost like an apartment building. We are trying to make the apartment like house into 1 address like a regular residential home. Is it possible to change the 9 electric meters into 1? And also change the divided cable TV line outside the house that the separates the suites into a single lincoming live servicing the house? And if you could guess how much it would cost that would be really helpful.

We cannot speculate price due to many variables.

Contact 2 or 3 local electrical contractors to provide estimates to change your multi-tenant service to one of the proper size.
