The hosted domains feature of a website hosting account denotes the number of registered domain names that you could include within the exact same account. Registering a domain name and hosting it are 2 completely different services although some people consider them to be the same thing. While the registration signifies that you become the owner of a certain domain name, the hosting part is what in fact enables you to have a website because this is where your data and emails will be. As these are two independent services, you'll be able to register a new domain name with one company and host it with another by modifying its name servers (DNS) - the domain address is going to work in the exact same way just as if it was registered and hosted with the exact same company. It is also extremely important to know that changing the hosting means pointing the domain name to another company and not transferring it.
