You can host multiple domains however this depends on your specific web hosting package, Host-1 does not support this feature but Host-2 and up do. Please check our website for the current limits for your web hosting plan.
All reseller hosting accounts, VPS and dedicated servers solutions can support as many domains as required. If you are a web hosting customer, login to your cPanel and look to see if you have any subdomains, parked domains or addon domains remaining that are available for use. If you don't have any remaining add-on domains to use, you can always upgrade your packge at any time from your customer portal.
