Because alcohol evaporates easily, and sucks some heat from your hand as it does.
Short answer: enthalpy of vaporization. I assume that by "spirit" you mean alcohol. The alcohol evaporates, and the energy for it to do so comes from the heat of your hand, so your hand cools slightly. You sweat for essentially the same reason.
Objects cool at a rate depending on the temperature difference between the hot object and its surroundings. Probably the hand is warmer than the air, so usually the object will cool faster in the air.
When spirit is poured on the hand, it evaporates quickly due to its low boiling point. This rapid evaporation absorbs heat from the surroundings, including your hand, causing a cooling effect and making your hand feel cold.
The heat from the flame travels through the air as infrared radiation and warms the front of your hand that is nearby. The closer your hand is to the flame, the more heat it will feel due to the transfer of thermal energy.
Hold your hand NEAR it and see if you can feel any radiated heat. Do not touch it!

Alcohol evaporates quickly, absorbing heat from the skin in the process, which creates a cooling sensation. This rapid evaporation leads to a drop in temperature on the skin's surface, giving the sensation of coolness.
because they might be vibrating and transferring energy from the leaf to ur hand
This type of heat transfer is called conduction. The transfer is from the warm hand to cool water.
Because the acetone takes some of the heat from your hand and uses it to evaporate.
The temperature differences - if the water temperature is cooler than the temperature of your hand, your hand will lose heat to the water. Furthermore, when the remaining droplets of water on your hand evaporate, it will also take some of the heat it absorbed from your hand.
