You can update, add, and remove some basic info on your account. You can change your name as many times as you want, but no more than 3 times in one minute. This limitation doesn't apply to accounts created less than 2 weeks ago. If you've already created a nickname, it's used if you don't have a name set.
How to change your name
Change other info
In a business environment, it's important that your email's display name represents you as a professional. For example, "PunkMusicFan" would not be an appropriate display name; instead, using your real name, such as Joey Ramone, gives your email a sense of professionalism before the recipient even opens it. If you find yourself needing to change your display name when using a Gmail email account, you can do so by navigating to the proper Settings option when accessing the account through a PC Web browser. There are no restrictions on how you're allowed to change your Gmail display name. Click the "Settings" icon, displayed in the shape of a gear, in the upper right corner of your Gmail account, and click "Settings" from the menu. Click "Edit Info," located to the right of the email display name you want changed in the "Send Mail as:" row.

The primary username in Gmail is the username you choose when you create a new email account. All email notifications are sent to the primary email address. Gmail allows you to enter alternate email addresses for email access. Should you wish to promote one of these to the primary username in the future, you must remove this alternate address from the existing email address list and create a new account using that alternate email address as the primary username.
Are you an Arabic speaker? Try the Android Gmail app in Arabic and tell us what you think. Important : The name linked to your email address is not your username. You can't change your username or email address. For example, if you get married, you could change from "Lisa Brown" at sportsfan gmail.
