Question

Answer 1

You are blowing the gas carbon dioxide into the liquid and they float

Answer 2

because when you blow you release air, when air gets in the water it go up because water is heavier than air, so does it form bubbles

Answer 3

Fats, oils and proteins in the milk stabilize the surface tension of the air-milk interface where the bubbles form at the end of your straw.  As they rise to the surface, these continue to provide stability to the thin film of milk surrounding the bubble, allowing a foam to form.
