You can run 5.0 and 5.1 just fine. The 5.1 versions of the Mathematica fonts are a superset of the 5.0 (and 4.2) versions. Specifically, every glyph that existed in the 5.0 fonts exists in exactly the same position in the 5.1 fonts, but the 5.1 fonts contain new glyphs, including the ones I mentioned below.
