the ice is going through a state called sublimation- it is turning staight from al solid (ice) to gas(water vapour). The fumes you see coming of is the water vapour
Yes.
Sublimation.
A simple example is to take 1 ice cube, which has 6 sides. Neatly cut the cube into 4 quarters (4 cubes). There are now 24 sides of the original single ice-cube exposed to the air, so melting should increase.
Dry ice sublimes when it is exposed to air. This means it changes directly from a solid to a gas without going through the liquid phase. As dry ice warms up, it releases carbon dioxide gas, creating the characteristic fog or smoke effect.
Dry ice sublimates, meaning it transforms directly from a solid to a gas without passing through a liquid phase. This process releases a dense fog of carbon dioxide gas due to the extreme cold temperature of the dry ice (-78.5°C or -109.3°F) as it reacts with the warmer air.

When ice is exposed to warm air, the ice will begin to melt and become a liquid once more
Yes.

Dry ice is solid form of carbon dioxide. Carbon dioxide will not kill you unless there is a sufficent amount present to replace the oxygen in the air around you. This will result in death by suffocation or asphyxiation.

The water at the top is more exposed to cold air than the water at the bottom of the ice tray.
