Would a rim from a 98' Cavalier fit on a 95' Mustang?

I have a 1998 Chevrolet Cavalier, will the rims with the tires on the rims, fit a 1995 Mustang.

Absolutely not

Nope, the two vehicles have completely different wheel bolt patterns, the Ford is 5-114 while the Chevrolet is 5-100. Simply not interchangeable.
