The term "main difference" is vague and subject to interpretation. I'll try to list a couple of what some folks consider "notable" differences.
1) Redhat Linux is normally purchased and various levels of support are also available for purchase. Fedora Linux is free (free as in beer as the saying goes).
2) Redhat Linux contains some features/enhancements not necessarily found in Fedora Linux or CentOS Linux - mostly these features are designed for enterprise environments.
Hope this helps.
What is the difference between Redhat Linux EL4 and EL5.

This very much depends on what you are trying to do. As a general desktop with no particular goals, Redhat/Fedora, Mandrake, SuSE, Debian and Ubuntu are more or less equally easy to use.
