Gandhar (Ganadhar) means the chief disciple of a Tirthankara. The exact list of Ganadharas is not the same in every Jain tradition, and traditions differ between Digambar and Śvetāmbar.

The most widely cited set is for Mahavira (the 24th Tirthankara), who is said to have had a group of Ganadharas led by Indrabhuti Gautama. Other named Ganadharas in that group include Agnibhuti, Vayubhuti, Sudharmaswami, Vyakta, Mandikata Mauryaputra, Akampita, Acalabharata, Metarya, and Prabhasa. This reflects a traditional lineup associated with Mahavira in many Śvetāmbara sources; Digambara texts often present slightly different enumerations for the Ganadharas of other Tirthankaras.

If you were asking for the Ganadharas of a specific Tirthankara (e.g., Rishabhanatha, Parshvanatha, etc.) or for a particular Jain tradition, tell me which one you have in mind and I’ll share the precise names as recognized in that tradition.
