Hi, I have ***@icloud.com and ***@me.com associated with my Apple ID but they are not the primary email - is there anyway that I can change the username *** for those aliases? I just don't like the username I chose when I signed those up so just want to change that part.
Once you have created an iCloud account (or in your case a MobileMe account) and chosen an @me.com/@icloud.com address to go with it you can't change the address (short of creating an entirely new account).
However, all is not lost. You can add up to three 'email aliases' - these are additional addresses (not accounts) which deliver into the same inbox as the main account. (In fact it's a good idea to give out alias addresses, rather than the main address, because if they attract spam you can easily change them.)
You should be aware before you start that once you've created an alias you cannot turn that address into a full iCloud account or move it to another account.

See the instructions below for changing an Apple ID.
Change your Apple ID https://support.apple.com/en-us/HT202667. Read these two sections very carefully to see what is allowed: If your Apple ID is a third-party email address and How to change your Apple ID if it ends with @icloud.com, @me.com, or @mac.com.
Before changing your Apple ID using a computer, sign out of all Apple services that use your Apple ID. If you are going to use an iPhone, iPad, or iPod, then stay signed in with your Apple ID on only that device. This instruction is taken from the above document under the heading Before you change your Apple ID.
For sign out purposes, see Where can I use my Apple ID? https://support.apple.com/en-us/HT202659 “This list is provided for informational purposes only and is subject to change without notice. It's not intended to include every feature or service that uses Apple ID. Visit the Apple ID support page for more information.”
