Add up the CFM for all the equipment and size your compressor for that. Then assume you are going to get twice as big as you are now, and then just go get a 60 gallon compressor
For full sized spray guns, I wouldn't go smaller than a Single Stage 60-Gallon with proper filtration/moisture dryers. I have one at home, and wouldn't go smaller if using even a single gun. When I was painting some trim and doors, it never stopped running while pulling the trigger. Just barely kept up. Ideally, look for a 2-Stage 80 Gallon, and proper filters and desiccant dryers.
