If you're just talking about the name in the user tags, and not the actual rights, you can change that by creating a page (or editing it if it already exists) at MediaWiki:user-identity-box-group- and adding the custom name there. You should replace by the group you want, for example sysop for admins, chatmoderator for chat moderators, or blocked for blocked users.
