The first pic is a grizzle hen (G), the darker bird could be a spread factor (S) or a dark t-pattern cheq, can't tell you for sure without looking at the tail.
The 2 difference in birds pic 2 & 3 is the pattern, pigeons pattern are barless, barred, cheq (pic 3) and t-pattern (pic 2).
The whites you have are pied white, a bit random in inheritance.

This is the freckled female. Is this a "color"?

And I call the one on the right normal colored, but is there something special about the dark one?

Here is the big white male :-) What is the difference between the one on the right (Gentle transitions of color) and the ones above (Sharp transitions of color)?

You can see some white on the top bird. There are 6 like that in the flock. On the bottom ones wing that is an interesting pattern. It wild?
