First, you should have only 1 Google account. You can have multiple Google email accounts, but an email account isn't a Google account, as far as the phone is concerned.

Second, remove an account and sign into that account to have it removed. Then on to the next one. You should be left with only the Google account you use for the phone (not for email).

If you have other email accounts, add them to your email app, or in that app's accounts in account & sync.
