Yes. I can see some red in the picture. It could be a red. I remember when I had 4 reds when they were very young, they were pink. 3 turned red/orange and one turned dark red. The one with the stripe could be a tirfasciata rainbowfish. It's going to be a beautiful fish in about 6 months.
If they are Australian rainbows, they are all female. Males have longer fins like the fins on the fish in the link I posted.
