Yes, you can have one or more wordpress on a site, you just install a second/third wordpress in a subdirectory, for example mydomain.com/mysecondblog/ . And with a little extra work you can configure your server that this subdirectory is reachable with a subdomain like: mysecondblog.mydomain.com . Or you can try installing wordpress mu, which allows multiple wordpress blogs.

out of the 3 options above which one is better?
