Go to the setting and change your username that must be unique

You mean your Facebook Name or Facebook Email?
Facebook limits changes in username, It should be base on your name.

You can only change your user name just once, if it's greyed then you already used it, no more changes can be done.

User name is a unique name to link to you, that can be choose as you wish but have to be approved by FB since it must be checked that no other person already use it.

You can change the username because you have reached the limit. You can change your username only once.
