"Admin" refers to users who can do things on the computer that non-admin users can't do. To delete a user, create an admin user. After you have created an admin user, open the System Preferences window.
In "Users and Groups" select the user you want to delete and click the minus sign at the bottom of the "Users and Groups" pane. You may need that user's password.
The admin password cannot be completely removed. Every computer requires an Admin username and password, whether or not you remained logged into that account permanently or not.
You can't unless you know the password. Then you can change it in System Preferences > Users & Groups
