It depends on the humidity. In very dry air the snow will "evaporate" and keep it cold. I would imagine it would need to be under 20% humidity. However, if the ground is warm, snow will still melt that is directly touching the ground. It may stick to grass for quite a while in dry air. A way to tell if its dry enough for snow is the "wet bulb" temperature, which is basically just a regular thermometer with a wet wick on it and measures the temperature that evaporation will occur. A wet bulb temperature below 32F is generally cold enough for snow even if the air is above freezing.

Yes
if it has been below freezing for enough time for the ground to be below freezing.
I have a hard time believing that there would be snow at 42degrees, even if it _is_ degrees F.

cant snow above freezing unless its really cold above the ground and its like 34 degrees at ground level but if the ground is frozen and it snowed at night and you got 3 inches and the next day it warmed up to 42 It would stick as long as the ground was frozen and as long as it didn't melt from being above freezing during the day.

It depends on what kind of surface the snow sticks to in above freezing weather.

No, the temperature has to be at least at freezing level.

no because the ground would be too warm
