I did a little research, and I believe that a SR lens will fit a MD mount. Can’t say for sure, but I as near as I can tell, the MD mount is a universal mount for Minolta lenses. They had several different ones, just as Canon had EFS, EF, and EFL But they all fit one camera. @JamesStaddon has good advice on inspecting the lenses, but since you already have them, I wouldn’t worry about them. They are both primes, and about the only thing that can misfunction on a old manual lens is the aperture ring jamming. If it works, and you can see the blades close down as you turn it, it’s probably fine.
