Your frogs look a bit young to be sure of sexes. They could be 1.1 but it's difficult to say. It'll be easier when they're older. Sorry, I know that's not what you wanted to hear.
The top pictured frog is a male, and if the last two are the same frog then they are female, the second to last looks really female and the last pic toes looks bigger but i pretty sure its the same frog right.
