Dragon's Blood and Angelina are both sedum, very different from sempervivum, and usually much easier to grow than sempervivum in your growing conditions.
Noid 3:
Looking good, except you might be keeping it to wet. What time of the day are you misting, and how often?
The little offset looks healthy. Cut off the stem, leaving just a short nub. Set it upright on it's bottom. It will soon start forming roots. Just don't keep it wet. Let it dry out between mistings.
Noid 4:
It is looking rather pale and etiolated, from lack of enough light and maybe to much water?
The little offset placed into a small pot is more correct looking. Be careful to not over water, and maybe give the etiolated ones some morning sun?
Noid 5:
This one also looks to be suffering from lack of enough light, it looks pale and etiolated. That would be why the offset stolons are so long, and the offsets are not forming nice plum rosettes. Be careful not to water to much. This one might also benefit from some morning sun.
I hope this has been helpful?
