Everything you say is true. The depth is way below parallel on the first, less so on the second, right at parallel on the third, then higher and higher for the last two. A common enough phenomenon. I'm sure you'll fix it (a little less weight for now maybe).
Yes, your shoes suck and the lack of stability is obvious. This will be fixed by a non-compressible sole. But you knew that.
Your hip drive and overall form (the running shoe tremors and gradually fading depth notwithstanding) look pretty good from here.
Your buddy spotting you is pretty funny.
