Someone knows about 4 song chord or tab? (guitar) (10 easy points)?

I have 2 questions. I recently started playing the guitar. So far I know that my minor, D major, C major, G major. So can anyone tell me a 4 song tab chord based on the chords that I mentioned earlier. Also a second question is … I'm not sure what chord is greater than the others. So you can list them from smallest to largest? I think it's E, G, C, D. … but correct me if I'm wrong = / Thanks for your time and effort in reading this issue.
