Most of those look like bikes bought for teenagers who outgrew them, mostly for men or women around 5'7" or so.

I'd be most interested in the Nashbar, but I'd check it out very carefully. The owner says a pedal is bent. That may indicate a crash. Check the seat, frame, handlebar grip, etc., on the side with the bent pedal. And check the crank to be sure it spins freely and evenly. Otherwise it looks like a good bike that would do nicely for years.

I'm 5'11" and can fit some medium frame compact bikes, but need to raise the seat post fully. Depends on the overall fit. You just have to ride it and see. Some bikes have enough adjustability in the stem and handlebar to make a medium frame fit someone 5'10"-5'11".
