I would say the bottom one is definitely female. A little hard to tell on the one above. I would put them together when you have a while to observe them. You could have two females, or a male and a female. Feed them well before you put them in together just to avoid squabbles over food. I'm no expert on these guys, but have kept several in the past. The males generally have recognizably wider jaws!
