Help sexing my fire bellys

[Aquaman7]

Hi all, I'm not very active in this forum at the time of writing but if I read many topics as I love urodele.
Now I have a group of 5 "Hypselotriton orientalis" and need help from the most experienced to know its sex.
I have some photos of the kiddies ...
Greetings!

To me, all except the 2nd one look female (ignoring the out of water photos), but better pictures of a side view would help.
I would also get some chopped worm into them to fatten them up a little bit

I agree with Aaron. In the second picture the cloaca looks swollen. Also the tail looks shorter and more compressed. The other pictures look like females as far as I can tell.
