Some Crassulas have that pyramidal growth..and sometimes a bit tricky to identify correctly, got to wait till the plants fully adapt, and show its actual growth pattern. The color variance of the leaves is also affected by how much sun/light it is getting. I am a bit thrown off by the lighting on your photos, the yellowish hue, casting a different leaf color. That is why I often try to get the photos done with natural light. For your no. 7 though I am leaning towards Crassula imperialis basing on the comparison photo you supplied.
I do have a couple of the plants you are trying to compare them with..see if they look like it, color-wise and growth pattern:
Crassula muscosa:
Crassula springtime: when I first goit it in late April 2013
C. springtime has been repotted and this is how it looks like this July 2013, the plant is the one toward the front, first photo showing side view and 2nd photo top view.
