Great photo!! Dosen't look like any of these gals were members of PETA!!
I count three Winchester Model 12s, two on the right end of the back row and one at the left end of the front row. The next gal in in the front row has a "Remington Autoloading Gun"/Model 11/Browning A5, and the middle gal has a Winchester Model 1897/97. The end of the magazine tube on the gun the gal at the left end of the back row is holding doesn't look right for a Model 12 Winchester. So, maybe a Remington or Marlin?
The Remington in the middle of the back row is either a "Remington Repeating Shotgun", a Model 1908 or a Model 10. The Model 8 was an autoloading rifle. I could go with the double next to the gal with the Model 10 being a Smith.
