I'm sorry, I can't make anything out of that. What do you want to know? How you can use templates from other wikis?
There is "Unused templates", "Wanted templates", "Uncategorized templates", and "Most linked to templates". I would like to "list all template" are available on the wikia site. I like to look at template on other sites to see how template being use and written. Now you have to through editing a page and go to the add template and the template edit window only show most use and all template. There is a "show used template", but it seem not to be working. It doesn't show any template used. It would be like a "list template:" in the template directory.
Going to Special:PrefixIndex on a wiki and selecting "Template" for the namespace should give you what you're looking for.
Another option is to browse through Category:Templates on the wiki in question.
