The cycle typically takes 4-6 weeks. Ammonia and nitrites will get high, which will burn the gils of your fish. That is just scientific fact. It might not kill them, but damage will be done. The damsels will do much better than the Tang, for a variety of reasons. Two weeks in, things are probably not bad enough that you would see anything bad happening. I would not think you are out of the woods yet...you are barely entering at this stage. The fish will be active and eat, so that is not a sign of anything.
Going to a larger tank for the Tang, will increase its chances of long-term survival, but it needs to go into a cycled tank, or that damage will just continue.
I don't recall seeing it yet, but two weeks in, what are your parameters?
