Just in case you didn't read my edit on your last post...
All moves in a Hip Hop video are choreographed therefore most of it is just "what feels right", not to mention the camera angles really do add an really big effect. You'll really need to join a Hip-Hop dance class where they teach you choreography step by step.
Alternatively you could learn a bunch of different style of Hip Hop (b-boying, krump, popping, etc.) and choreography will come to you naturally (Like it did for me

.)
I suggest you learn how to Glide first, since its very simple footwork. Then learn a couple C-walking moves which is a bit more advanced but nonetheless easy footwork. After that you can move onto some hand motions like Tutting and Arm waves. After a couple of months choreography will come to you naturally and you'll be able to come up with your own routine.
BTW, let me emphasize on how much camera angles make the moves look good on a music video. IT MAKES IT LOOK A LOT FREAKING BETTER AND COMPLEX THEN IT ACTUALLY IS. don't base your moves off of music videos, base it off videos like http://www.youtube.com/watch?v=PkUnoG-wm... my personal favorite
