I have some shelves that I can't figure out how to arrange, how would you put them?

I have a bunch of shelves my friend bought for me and I am not so good with this kind of stuff so I was hoping for some suggestions from someone who may have had similar shelves or is just good with this kind of stuff. My living room has two open walls where the shelves can go, they are the left and the right walls.
I have:
1 Large shelf that is shaped like two rectangles on top of each other,

2 cube shaped shelves

6 L shaped shelves

and 1 that look like an L with a longer bottom like: |________

I know this is an odd question but if anyone has some feedback, that be cool. Thanks!
