Forgive me if this isn't what you were looking for, but I'm not sure what you mean- but I AM pretty proficient with photoshop, so I wanted to try to help!
Create your first one exactly how you want the rest of them to look then just duplicate the layer. (Right click on the layer and select duplicate..) Move each layer so they they're all lined up.
Then do the same for the letters. Do the first one, then duplicate the text layer, edit it and change the letter and move it over to the appropriate background. HTH!
