Three answers:

A server can only be connected to one "config database", meaning you can only run one FARM instance.

A server can host multiple SSPs, so you can run multiple SEARCH, USER PROFILE, MY SITE instances. Not recommended though.

A server can host as many web applications (websites) as you'd like.

We've been running multiple instances on different ports, no problem. Great for development. But we haven't been running different versions of SharePoint on the same server

You can run multiple web apps on the same server, provided they use different ports and / or different host headers. They will both be part of the same farm however...

If you mean by two SharePoint 2007 instances two installations of the server, then the answer would be no. If you mean two completely different sites with different sitenames, that is possible by making use of hostheaders for each of your web applications. Running SharePoint 2003 and SharePoint 2007 side by side is possible. I haven't tested running SharePoint 2010 next to SharePoint 2007/2003 though.
