You are sort of correct. I missed that second part; the first part looks like it is still asking about Achievements. What they are asking about in the second part is not custom user rights but custom user group tags. To do that, simply change the corresponding system messages. You can see a list [ here]. To edit a message, once on your wiki, go to "MediaWiki:message" (where "message" is replaced by the message name as indicated in the list). Then edit/create the page with the text you desire. Note that only plain text is acceptable. Attempting to format the tags (ex. change their color) though use of wikitext/HTML will not work as such additional characters will be interpreted literally as part of the tag. If you want to change the appearance, that needs to be done separately using site CSS.
