What breed/s are these?

Hi all, these are our 9 hens and 2 roosters!
We're pretty sure it's 9:2. There's one my uncle seems to think is a rooster instead of a hen
Anyway, I want to know the breed/s if anyone can tell me. I know they pictures aren't too great, but they don't like humans

Our brooding hen!

The one up the back is the one we're unsure of

This one is our smaller rooster and another hen
A better picture of the hen my uncle isn't sure about. She's a hen, right?

Sorry the pictures are so bad, I took them on my phone and these hens don't like people.
We used to have a really beautiful black hen with green through her feathers, but she died two weeks ago. I don't think any of the babies came from her, but just in case that helps.
Also, if it helps, I'm in Australia.

 

Ah, three roosters, great! Lol. The other two annoy the hens, but seem okay with each other most of the time.
Thank you both of you!
