    Sure, especially if it had liquid water on the surface, Mars has less than 1% of Earth's atmospheric pressure and it has at least a little  precipitation

    Yes it could.  Mars has clouds, although it doesn't have water snow - but it is cold enough at the poles for the air (mostly CO2) to become dry ice.

    Yes. Liquid water is possible down to 1% of our atmospheric pressure although the boiling point in the situation you describe would be very low.
