Sexy time Saturday - unknowns PART 2!

I tried this last August and had some success so I thought I'd dust off some more pics from the archive and put your knowledge to the test. As with last time, I have absolutely no idea who these women are so it's up to the readers to clue me in to their identity.  No snipes on the backs of any of these images to provide me with any clues (here's the post of the other unknowns):

 UPDATE:  Well, that didn't take long.  In less than 24 hours, we got 'em all named.  THANKS TO EVERYONE WHO HELPED OUT!

Dixie Dunbar, thanks Rob!

from "The Hollywood Review of 1929".  Thank you Ed Watz!

Rich Finegan chimes in and let's us know this is Paula Prentiss from the 1964 Universal feature "Man's  Favorite Sport?", but dukdukgoose informs us in the comment section it might be Charlene Holt................who's right??

From the always amazing Steve Massa - "Hi Louie - Still number 4 is from a George LeMaire Comedy, an early sound series released by Pathe in 1929 and 1930. That's George LeMaire with the glasses and white jacket, and to the right in the funny hat and shawl is Louis Simon. Not sure which title this is, and don't recognize any of the girls."

Thanks to Richard M. Roberts for letting me know that the still is from "Go Easy, Doctor" (1929)

from "Rio Rita" (1929), thanks again to Ed Watz!!

Barbara Bouchét in "Agent From H.A.R.M." (1966), thanks Jack Theakston!
