Step-By-Step 

To add / remove / manage your email accounts, first go to your cPanel. 

Your login is usually the first eight letters of the domain name.  You can find it in your welcome e-mail.
Your password is assigned to you when you first sign up, and can be changed upon request.

Once you are logged in to cPanel, you will see a list of icons for all of the features on your account. The first icon you see is labeled "Mail" and this is the one you'll want to click. This takes you to the Mail menu.

Once in the Mail menu of cPanel, you will want to click on the link that says "Manage / Add / Remove Accounts." This will take you to a list of your current email accounts that are setup and give you options for each account, such as the ability to change the users' passwords.

At the very bottom of the list you will see a link for "Add Account." Click this and you will be taken to a screen that will let you add the email address and assign a password.

One option it will ask for is quota. The quota should be at least 10 MB and generally no more than 100 MB.
