Hi, I'm Mike and I'll be assisting you. Please stand by while I review your question.
The minimum service to a living unit with a kitchen is 100A.
No, you'll need 100A SER. That is a 4 wire cable. 2 hots, 1 neutral and 1 ground. Your house service and panel are too small for 4 apts and a house load.
