Yes you can have up to 10 domains all pointing to the same website and mail domain from the Standard Hosting Package.
However, as Google and other search engines will mark you down for duplicate content for having multiple domains point to the same website I would suggest using Web Forwarding with a 301 redirect to your main domains website for better search engine optimisation.
You would usually setup Web Forwarding with your Domain Provider, but check to see if they offer a 301 redirect and not a 302 for the service. If they do not then you can always transfer the domain to us and setup the Web Forwarding through your Registration Domain Manager.
