Are these female button quails?

[Julzzz]

I have 2 of these kind and they look almost identical. Are they females? Do male this color even exist?

Also this white with black spots? Female or Male ? (Its next to 2 males)
It has no red vent feathers.

Some of the color mutations are nearly impossible to sex on looks so listen for crowing; shouldn't take long. No crowing it's likely a hen

Only the males make the spooky, wind whistling call. Both hens and cocks will make a "Pew, pew" sounding call - there's apparently a difference between them but I could never figure it out, so listen out for the whistling wind noise.

Pics 1-3 are red-breasted females.

The males look like this

I have a male that looks like this (pic attached)
Is your male the same as mine, but without a bib?

Your male looks like a normal wildtype.
Here's my male wildtype. The hen next to him is the female colouring.

Yea. Mine is very similar to that one. They are very beautiful birds you have. My birds are about 7 weeks old and the female still doesn't lay eggs. When is she suppose to lay? My aquarium is 10 gallon with 3 birds, do they need more space?

The first 3 pics show a female red breasted as Quailobsessed said. Males in that color don't exist. I actually think the last two do as well, it's just combined with tuxedo in her, so you only have the color on her head and back to go by, but it seems to be the same color = males in that color don't exist - the closest thing you'll get in male is something like this guy and he is the only one I've seen looking that much like a female red breasted:
