• In Jainism, Ganesh (Ganapati) is not a Tirthankar or a jina. He is not considered a liberated perfect soul who will become a jina in the future.
• There are differences between traditions:

- Śvetāmbara: Ganapati is worshipped in many auspicious beginnings and ceremonies; images and rituals for Ganapati are described in some Śvetāmbara works. - Digambara: Ganapati is generally not a prominent figure in their canonical texts, and he is not treated as a jina.

• The Jain view on jinas: in this cosmic age there are twenty-four Tirthankaras; no new jina is expected to arise beyond them.

If you’d like, I can look for a specific Jaintext reference or a JainKnowledge page that discusses Ganesh in Jainism.
