Answer

For Bhagwan Parshvanath, the Śvetāmbara tradition clearly gives 8 Ganadhars: Subhadatta (Subha), Aryaghoṣa, Vasiṣṭha, Brahmacāri, Soma (Saumya), Śrīdhara, Vīrabhadra, and Yaśas. ( jainqq.org)

For the Digambara tradition, the sources I could verify state that Parshvanath had 10 Ganadhars, and Svayambhu was their chief. However, the name-by-name list of all ten is not preserved consistently in the sources I verified, so I should not invent the remaining names. ( jainworld.jainworld.com)

Explanation

So, in short:

• 8-member list: the commonly cited Śvetāmbara list above. ( jainqq.org)
• 10-member tradition: Digambara sources affirm the number 10 and the leader Svayambhu. ( jainworld.jainworld.com)

Spiritual Understanding

This shows that Jain tradition preserves Parshvanath’s sangha with great reverence, but also with sect-wise textual variation. The heart of the teaching remains the same: the noble path was organized, carried forward, and preserved by the Ganadhars. ( jainqq.org)

Takeaway

If you want, I can next give you the 8 Ganadhars with their order, or a comparison of Śvetāmbara vs Digambara views on Parshvanath’s disciples.
