I saw that you asked about these templates on talk pages. Cleaning up our unused templates has been a long time on my to-do list so it's good you're looking into it. I don't have time to check all those at the moment but I'll give few points to help you.
 * Templates are listed as non-portables if they are marked as infobox type. See Help:Template Types. With a quick glance I don't see any infoboxes so we should just change the type to more appropriate. Remember that this portability thingy concerns only infoboxes, Help:PortableInfoboxes.
 * To see where template is transcluded use What links here. For example Special:WhatLinksHere/Template:Comic_Colon/t reveals that the template is called by Marvel Database:Automatic Image Template.
 * If the template isn't transcluded anywhere it still could be used by substituting it. For example, somebody could subst Template:FF 1 on comic appearances. I still doubt that's the case in this example and deleting this kind of template isn't a problem. It could always be undeleted if the user of that template wants.

Please ask if you have any questions.
