Yes, Will Byers has powers in Stranger Things. In Season 5, Volume 1, it was revealed that Will possesses telepathic abilities similar to Vecna and Eleven.

Will's Powers

Will can control creatures from the Upside Down using his mind. In the episode "Sorcerer," he demonstrates his abilities by taking control of Demogorgons—freezing them mid-air, lifting them, and contorting their bodies in the same way Vecna manipulates his victims. He experiences the signature nosebleed associated with using these telepathic powers, just like Eleven does.

Origin of His Abilities

Will's powers stem from his connection to Vecna dating back to Season 1. When Will was trapped in the Upside Down, Vecna inserted one of the dimension's tentacles into his mouth and injected him with what appeared to be Upside Down material. This explains why Will coughed up an Upside Down slug at the end of Season 1 and established his link to the hive mind. Throughout earlier seasons, Will displayed what fans called "true sight"—the ability to sense the presence of Upside Down creatures and see visions of that dimension.
