You should definitely only copy templates in the source editor, not visual editor. There is an option on Special:Preferences to always use the source editor.

Once you find a template you like, you should be able to view the template source and copy it to your website.

But always remember to attribute the copied template - they are licensed under cc-by-sa, and copying without attribution is a licensing violation.

If you link to a template you like, and the wiki you want it on, I can help you.
