What Spanish word can describe a male member of a quinceañera court?

A male member of a quinceañera court can be called a chambelán.

Chambelanes are male attendants who support the honoree during formal portions of the celebration. They may appear in coordinated clothing, participate in choreographed dances, join the entrance procession, and pose for official photographs.

The term describes a court role, not the person whose birthday is being celebrated. That distinction matters because quinceañero refers to a male honoree, while chambelán identifies an attendant. Other regional or family terms may also be used.

Modern quinceañeras frequently adapt gender roles and titles. A court may be mixed, single-gender, informal, or replaced by close friends and relatives without traditional labels.
