Well, many people will find some of the tricks you listed as easy, intermediate, or advanced. I say this because your asking a very subjective question (what is intermediate?).
Rather than giving you an answer, I'll just say this: play around with what you can do.
For an answer (or example) to learning some combination moves, try doing mini-columns after/during: a) a sprinkler exit; b) leg orbits; c) antisuicde. You say you can do these tricks, so try combining two of them together.
