These are somewhat irritating, due to poor resolution. I'm not good enough with shadow time analysis to tell whether or not WTC 7 was still standing when some of them were taken or not. It is clearly later in the day than most of the other shots from this area which I've seen, and I do think that many of these were taken on September 11th rather than later, due to the firefighting and lack of cleanup (which started, at least to some degree on the 12th, based on other pics I've seen).
Anyway, for whatever these may add to the knowledge pool, here they are:

This one seems to be while 7 was standing:
