The question is unclear - Which, if not both, temperature waters are insulated? Do the insulations, if both, vary?
I am assuming we are purely talking liquids freezing here rather than including vapour.
Cooling water down relies on the transmission of heat away from it so, assuming similar insulation:
Other combinations - No, cold would freeze first.
In similar conditions, hot water still has to loose the heat energy and become cold in addition to the time to chill from cold to frozen.
Hot uninsulated vs Cold insulated - Possibly, depending on the insulation.
If the energy loss were reduced for the cold water then if could be the case that hot water would freeze first.

Sugar water freezes faster than fresh water due to the presence of sugar molecules which disrupt the formation of ice crystals. This phenomenon is known as the Mpemba effect, where the solution with a higher concentration of solute freezes faster than the solution with a lower concentration of solute.
Plain water freezes faster than dirty water because impurities in dirty water lower the freezing point, requiring it to be colder before it freezes. This means that plain water will reach its freezing point quicker and solidify faster.
water freezes faster than tea because unlike tea, it has no additives or chemical compounds in it. Therefor, there are no "barriers" in the freezing process of water and therefor, it freezes faster than tea.
regular water!:)
Test it yourself
Cold water freezes faster then warm water.
Sugar water freezes faster than fresh water due to the presence of sugar molecules which disrupt the formation of ice crystals. This phenomenon is known as the Mpemba effect, where the solution with a higher concentration of solute freezes faster than the solution with a lower concentration of solute.
I think it is fresh water freezes faster because the salt melts ice.
probably water

Sugar water freezes faster than salt water. However, regular tap water will freeze faster than either salt, or sugar water.
Cold water. It doesn't have to cool as much as hot water does, thus it freezes faster. Under VERY specific labratory conditions, it can be made possible to have warmer water freeze faster, however, these conditions will not be present when you fill your ice tray. If you want ice, use cold water.
