Why a person feels cooler when he pours a little spirit on his hand?

Cool off faster in the air or your hand?
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.
Why is it that when spirit is poured on the hand you feel cold?
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.
Why if your hand is held near to the side of a flame does the front of your hand feel heat?
