That's one of the old models that has the eye controlled AF point selection. http://www.canon.com/camera-museum/camera/film/data/1991-1995/1992_eos5_qd.html?lang=us&categ=srs&page=eos&p=2
Any regular EF mount lens will work on that body but the new ef-s lenses designed for the newer crop bodies won't.
You could start with a 28-135 or a 70-200, it's a 35mm film body so there is no "crop" factor.
Just make sure if you buy a non Canon lens it's got the regular EF mount, and it's not designed for a crop sensor only or you could get vignetting.
