Can I host domain names on WHM cPanel Admin Cloud account or do I need cPanel accounts for each domain name?

Hello Forum. I have got a cPanel Admin Cloud (5 Accounts) license. I want to host about four or five domain names (i.e. mydomain1.com, mydomain2.com, mydomain3.com, mydomain4.com, mydomain5.com), or web sites, on my server hosting. Question 1) Can I manage or host the domain names from the WHM root account without purchasing an additional cPanel license? Question 2-a) If the answer to Question 1) is Yes, meaning that I do not have to purchase an additional cPanel account, can someone tell me the steps to follow to add the domain names? Question 2-b) If the answer to Question 1) is No, meaning that I do have to purchase cPanel account(s), i). can I host all five domain names on one cPanel account or ii). do I have to have a separate cPanel account for each domain name? Thank you in advance.
