Top left, looks too featherfooted and squat built, almost like a feather footed bantom. Breed name escapes me.
The top right, look like Leghorns. Then again, many times Maran cockerels go through a very akward teenage gangly stage, so those "might" be.
The bottom pic looks like a Cuckoo Maran.
You need to go see the birds in person, those picture are all so different they aren't their birds, I think they were pictures to be examples of the colors she had available.
