I'm quite new to this. Can it support more than 3 zones? Or is 3 zones good enough for all situations?

Have you installed this module?

I have used this module and set up shipping with 35 zones! All are working perfectly!

Suggestion: set up all the zones you need then uninstall the Zone Table Rate and then install it again - your zones should be available to work with.
