You need to do a load analysis to see if one of the existing services is big enough (amperes) to serve both a portion of the existing 8 family building and the new 2 family building.

Note that the existing services may be inadequate to begin with; they would be grandfathered to continue to serve the existing 8 family. Any significant addition would require being brought up to modern code. Generally an apartment needs a 60 to 100 amp panel or subpanel depending on size and local code.

So by putting in a new service for the new building the existing services can be left as-is.

What you need to do is contact a qualified electrician. He can give you a proposal as to what would need to be done and what he would charge. Agree on a price and have him do the work.

This is NOT DIY work.

Yeah, but I just changed three single pole switches without any extra help!

Sounds like you will be good to go after staying at the Holiday Inn.
