There's a lot of chicks there all huddled together, and without a good numbering system, and we can't see legs and feet, plus a lot of chicks look very similar at this age, that's a bit of a tall order...I *think* I see some Buff Cochin, possibly Partridge Rock, maybe Australorp if clean legged, possibly Buff Orpington if clean legged....but it's too hard to tell in the huddled masses.
It might be best if I give you some resources that you can compare to your chicks as you will be able to see them up close...otherwise you will have to take single pictures of each chick (or chick type).
This is a good identification page:

Then of course go to Ideal's website and look through the photos of breeds they offer, especially in your pack.

If all you can see is the general breed, then going to Cackle Hatchery can really be helpful as they have videos of chicks for each breed they sell.

Congratulations on your new chicks!
