Help identify two day old chick breeds

[Shox820]

Just got an unexpected delivery of chicks. Long story short I ordered a black sexlink, a barred rock, and 5 of a rainbow assortment. Cancelled the order in feb and got my money. Found a local flock and these babies show up yesterday. Someone didn’t actually just cancel it on their end. They also sent an extra. So not sure which are which. Thinking the blonde ones are leghorns maybe. I think they typically include EE’s and a dark layer in their assortments. Thought on what these are?

The Barred Rock is the black chick with the dot on its head. The 3 other black ones are likely Black Sexlinks but could be a different breed from the Rainbow Assortment. The blonde ones certainly could be leghorns. And no idea on the other two, so I'm gonna guess EEs.

I think the light brown is a welbar which it looks the same as our other welbar did. No clue on the dark brown one with the fluffy cheeks
