[Thamnophis]

Because the spots on top of the head look "big" and are not touching eachother I think that the first one is no T. sautritus, but a T. proximus. But A detailed picture of the side and top of the head would help to make sure.
In T. sauritus these spots are very small and mostly touch eachother.
The other snake looks like a T. sirtalis parietalis.
