penguin is a tuxedoed blueface. If he has red vent feathers he is a boy but they don't normally get those until 4 or 5 weeks old.
Puffin is a tuxedoed redbreast. Tuxedos don't always get red vent feathers but at this time it looks like a girl. Kind of early to tell at 2 weeks old.
The 2 lighter ones look like cinnamons but it's hard to tell at this age. Again, it's too early to tell the sex since they don't normally get colored vent feathers until closer to 4 or 5 weeks.
Little dark chick looks like a cinnamon blue face.
That's what I was thinking! Lol when the five of them were all together those 2 would be by themselves and they're always cuddling and what not. That's why I'm pretty sure puffin is a girl. And so far they are very happy together!
