That looks like a group of Manouria tortoises...either Manouria emys emys or Manouris emys phayrei. It is sometimes hard to distinguish tortoise species by looking at the hatchlings. Is there any way you could post a picture of the adult tortoises?
Well, I tried to save the picture to "My Photos" but its a facebook picture and shows up in my file as an un-opened file. I'm not able to get it for you. For those with GOOGLE chrome, you right click on the rectangle image and choose "open image in new tab" Then look up at the top of your screen and you'll see a new tab that you can click on. The picture show up.
I'm thinking that the baby in the upper left corner is a box turtle.
