Orange bellies = female. But because I am on my phone and you didn't label the pictures as to which one is which I can't say fore sure what you have. But from one pic you do have one female.
Pics 4 and 5 look like a male to me the rest are defiantely female. One male and one female IMO.
If it has any orange in the belly = female, as cage says.
No orange = male
They look large enough to have started developing colour, so if they haven't got orange now, it's likely they wont get it at all.
Cool. Thanks guys that's what I was hoping for when I picked them out. I did some research on them a while back. When I saw the colors on them I actually had them backwards. I thought the darker one with the orange on the belly was a male and the lighter one was a female.
