In Hef's world, there's a distinct difference between a girlfriend and a Playmate. Three of the those five are girlfriends....Holly (in the first pic), Bridget (back towards camera in 2nd), and Kendra (far left, 2nd pic). The other one with her back to the cam in 2nd pic I believe is Bridget's sister (not a girlfriend or a Playmate).
