Sounds as if you were trying to repeat the MpembaEffect. Apparently it was even known to Aristotle that to get a liquid to freeze faster, "warm it in the sun first".
Enter Mpemba (circa 1950s?) who had known that warm liquids freeze faster than cool ones when placed in the frig.
Much experiments and $$ later, the explanation is yet to arrive (maybe a Nobel?), but the optimum temps for the experiment are 35oC for the hot liquid and 5oC for the cold one.
Cold air and hot water makes water freeze faster simply because the hot water is steaming and so the result is that there is less water to freeze. hot water = steam = less water less water = faster freeze cold air = faster freeze
Hot and cold water and a freezer and a timer or stopwatch
warm water because the cold water will freeze the cell wall.
Cold water will freeze faster. Because the freezing point of water is 0oC, water that is closer to that point will freeze faster then hot water. This is because it will require less time to lower the temperature to the freezing point.
The fact that hot water may freeze faster than cold is often called the Mpemba effect

cold water
Cold water freezes faster because hot water has to cool down to the freezing temperature before it can freeze.
It has been proven that hot water freezes faster than cold water.
Kinetic energy
yes

No. It takes longer to freeze because cold water is closer to it's freezing point.

Cold water will freeze faster. Because the freezing point of water is 0oC, water that is closer to that point will freeze faster then hot water. This is because it will require less time to lower the temperature to the freezing point.
Cold water, being the closest to freezing point, will obviously freeze the fastest. Hot water will freeze the second fastest, and salt water barely ever freezes, except in very cold conditions.
