Welcome Tony!
Both your birds are gorgeous little fluffs and i agree with you if Tommy is the bottom photo (lovely looking yellow-sided) but Ruby (assuming the top is her) isn't a green cheek. Someone might know better but I'd put money on Ruby being a Black Capped Conure. They're in the same part of the conure family tree but Black caps have a dash of red on the top of they wings and pointed chest feathers (which is what Ruby looks like to me from your photo).
The only thing throwing me is Ruby's feathers around her ear, normally Black Caps don't have markings there, while Green Cheeks do but I didn't think it got that pronounced. But i making a mountain out of a mole hill.
Yours conures look adorable.
