I'm want to simply add a Motion Graphics Template from Adobe Stock. It says it's optimized for Pro Premiere. I will only want to add these occasionally. Can I edit these in IMovie /Photoshop which I already have? I'm a Photographer who is just beginning to learn video, etc. Thanks in advance.

You can't really "edit" motion graphics templates other than the parameters which are available in the templates themselves. You can create new motion graphics templates directly in Premiere Pro or slightly more advanced ones using After Effects.
