blowing cool air, is the air only in your mouth... warm air comes from your lungs. temperature also varies by how open your mouth is while blowing air out
Blowing out "haaa" feels warm because it involves the mouth producing warm air from the lungs. On the other hand, blowing out "phooo" feels cool because it involves the process of evaporation of saliva from the mouth, which cools the air as it exits.
Blowing on your hands increases the rate of evaporation of moisture on your skin, causing a cooling effect. However, the heat from your breath can also warm up your hands by providing additional thermal energy.
The air you blow is about 30C, if your hands are cold, their temperature will be lower than that, therefore, blowing 30 C on them will warm them up. If your food is too hot, it is above 30C (can go as high as 100C or more), blowing 30C on them will cool the food faster.
Frostnipped fingers are helped by blowing warm air on them or holding them under one's armpits. Other frostnipped areas can be covered with warm hands. The injured areas should never be rubbed.
