It looks like you have three adorable DSH kitties (domestic short hair). My oldest cat Dudley looks very much like your kitty in the last picture. Most people refer to that color pattern as a "brown tabby" or Maine Coon mix.
Your top kitty looks to me to be blue, and I love that color as well. And your second kitty looks like a dilute tortoiseshell (gray/blue and orange/cream instead of the typical black and red).
