Yes, you can edit each template on its own page. Some templates contain templates (just to be confusing) so you sometimes need to work back to find the pages to change. They can get very very complex, so it's something to do carefully, and with the help of someone who knows templates well if necessary.

There are help pages about templates and infoboxes in particular. We also have a webinar about templates[ (which mentions infoboxes.

But the best resource is our community forums. There are lots of past questions about infoboxes, and plenty of people who visit there who know a great deal about how to make the changes you want :)

I hope that helps!
