Answer

In Jain tradition, every Tirthankar has Ganadhars — chief disciples who understand and organize the Tirthankar’s teachings into the Jain Śruta tradition.

However, the complete list of every Ganadhar of all 24 Tirthankars is not uniformly preserved in commonly accepted tradition in a way I can present with full certainty.

The most clearly and widely known Ganadhars are those of Bhagwan Mahavir Swami, who had 11 Ganadhars:

• Indrabhuti Gautam Swami
• Agnibhuti
• Vayubhuti
• Vyakta
• Sudharma Swami
• Mandit
• Mauryaputra
• Akampit
• Achalbhrata
• Metarya
• Prabhas

Explanation

A Ganadhar is not an ordinary disciple. In Jain Dharma, Ganadhars are the foremost disciples of a Tirthankar. They possess extraordinary knowledge and spiritual capacity, and they explain the Tirthankar’s divine preaching to others.

For Bhagwan Mahavir, the 11 Ganadhars are especially important because the Jain Āgamic tradition is connected through them, especially through Sudharma Swami, who continued the lineage after Mahavir Swami’s nirvana.

Takeaway

Sorry, I can only provide information that is clearly established within Jain tradition. The names of Bhagwan Mahavir’s 11 Ganadhars are clearly known, but I cannot safely provide a full list of every Ganadhar of every Tirthankar without risking inaccuracy.
