I think it was reported in 10Qs that there were no suspension periods went thru, imo. Also see in 10Qs that there are $2 warrants pending to exercise by the retail investors.
I believe the answer is yes to all 3 questions. A bunch expiring now and the next days, some expiring in Dec, and some that are more long term. Mine in particular are good to Nov '22 and some to Feb '23. I have no idea how large any of these groups are. Of course there are also the insiders most of whom have much longer terms.
