Can you see if a person has artharites in his spine just by exarys?

Yes, you can. You can actually see quite a bit from an xray of the spine, including osteoarthritis. You can also look for some stability issues, minor fractures such as a pars fracture, alignment, general disc heatlh, etc. I hope that helps!
