No, the glossopharyngeal nerve (CN IX) is not the only cranial nerve that contains sensory fibers. Other cranial nerves, such as the trigeminal nerve (CN V), facial nerve (CN VII), vestibulocochlear nerve (CN VIII), and vagus nerve (CN X), also contain sensory fibers in addition to motor or mixed fibers.
glossopharyngeal nerve (IX)
The glossopharyngeal nerve is responsible for providing sensory information from the back of the throat, taste sensation from the back of the tongue, and motor function to some of the muscles involved in swallowing. It also plays a role in regulating blood pressure and monitoring oxygen levels in the blood.
The trigeminal nerve (cranial nerve V) is a mixed cranial nerve that contains both sensory and motor fibers. It is responsible for sensation in the face and motor functions such as biting and chewing. The sensory component detects touch, pain, and temperature from the face, while the motor component innervates the muscles of mastication. Other mixed cranial nerves include the facial nerve (VII), glossopharyngeal nerve (IX), and vagus nerve (X).
A mixed nerve, such as the trigeminal nerve, contains both sensory and motor fibers that can send and receive messages. These nerves are responsible for carrying both sensory information from the body to the brain and motor commands from the brain to the muscles.
The ventral ramus of a spinal nerve contains both sensory and motor nerve fibers. These fibers innervate the muscles, joints, and skin on the front part of the body.

Glossopharyngeal cranial nerve
The vestibulocochlear nerve (CN VIII) contains the sensory fibers involved in hearing. It carries auditory information from the cochlea of the inner ear to the brain for processing. Damage to this nerve can result in hearing loss or other auditory issues.
facial nerve`s branch - Chorda tympani provides parasympathetic innervation to submandibular gland and sublingual gland and special sensory taste fibers for the anterior 2/3 of the tongue glossopharyngeal nerve whitch receives special sensory fibers (taste) from the posterior one-third of the tongue
