I would not suggest seperating them until they are a decent size usually 1 foot tall or more. They should be fine growing in a clump till then. Pluse if your in a colder state it is always best to wait till spring to start seperating plants like this.
I have found with most TC things that if you get a few plants fairly fast out of one plant it is probably seperate clones. In most cases when recieving plants they always seem to have just one small plant per cell. But in some cases were they are pushing them hard you get tons of small ones. I have some photos of some growing in clumps that were all from one cell and their seems to be a few different forms.
