For anyone coming across this later on, the extensions mentioned by Veralann are good if you want to add additional "user groups". However, if all you want to do is change the text displayed for actual user groups (those listed here), creating/editing the pages listed [ here] is a simpler solution. Note that these pages are in the MediaWiki namespace so be sure to put "MediaWiki:" at the front of the name when trying to navigate to them.
