First one does look a little like Haze to me, but I'm not 100% sure... Second one is totally famous, but I'm drawing a blank on her name. Other than that, I only know 5 and 6 for sure, and can only venture a guess on 7.
6. is indeed Roxanne Blaze. (and Justine 2 was indeed fantastic)
7. looks at first glance like Kaitlyn Ashley (the dark, full eyebrows), but I don't know if she was around when Francesca was that young. Might be Laurel (or Lauryl) Canyon?
(btw, don't rely on Search Extreme for comprehensive filmograhies - as evidenced by the whopping list of two films listed for Roxanne.)
Also, I thought we weren't allowed to post explicit images here. Granted, I haven't visited for a while. Did I miss a memo?
Picture 1 is Heaven Leigh in her later days; picture 2 is Blair Segal; I dunno the couple; the scrotum cruncher is Melissa Melendez; the Cheyenne Silver impersonator is Paisley Hunter; picture 5 is Roxanne Blaze; I concur the girl with Francesca is Nikki Wilde; can't place the Playboy model.
