They all look to be syrians to me.

Maybe you mean different varieties????

They also seem about average size for syrians.
My Tarzan is quite a big boy.

I have four at the moment.
Tarzan...dark grey merle
Jayne.....Black dominant spot
Greystoke...She is the 'old' black. Meaning she isn't jet black but a washed out colour.
I also have one of Jaynes baby girls who isn't named yet.
My babies are always cuddly tame because I get my grandkids to tame them at 4 weeks old. They've never been bitten even by a baby.

I have 5 robo's as well but they aren't named as I can't tell them apart.

Good on you for giving homes to hamsters needing homes.
