The olfactory nerve which is also cranial nerve number 1 is responsible for the sense of olfaction.
The information of the equilibrium reach your brain via vestibulocochlear nerve. It is the eighth cranial nerve.

Cranial nerve number 2 is the optic nerve, responsible for most of the sensation of sight.
Cranial nerve 7 is also referred to as the facial nerve. It has both sensory and motor components. Its sensory portion is responsible for taste on the anterior two thirds of the tongue as well as sensation for a small patch of skin by the ear.

The third cranial nerve, the oculomotor is responsible for blinking and most other eyelid movement.
The cranial nerve responsible for moving the cheek muscles is cranial nerve V (the trigeminal nerve). However, cranial nerve IX (glossopharyngeal) and cranial nerve XII (hypoglossal) are also involved in moving the tongue, the throat for swallowing and the muscles along the floor of the jaw.
