The hosted domains feature of a website hosting account indicates the number of registered domain names which you can add in the same account. Registering a domain address and hosting it are 2 different services although many people consider them to be the very same thing. While the registration ensures that you become the owner of a specific domain address, the hosting aspect is what really permits you to have a website as this is where your data and e-mails will be. Because these are two different services, you'll be able to register a new domain with one company and host it with another one by changing its name servers (DNS) - the domain name shall work in the exact same way as if it was registered and hosted with the exact same company. Additionally, it is very important to know that changing the hosting means directing the domain address to another company and not transferring it.
