I'd be willing to bet that chicks #1 and #3 are your Easter Eggers, also that #4 is your Swedish Flower Hen (and a very cute light golden SFH at that
) Also I would agree with you that chick #2 is an Egyptian Fayoumi because of its smaller stature and coloring, the only other bird I think it could be is a Partridge Penedesenca but I think the EF is more likely. It can be hard to identify chicks because of the great variety of colors in them, especially at hatcheries, but with a little research you can be reasonably sure in your guess.
