In Jain Dharma, “24 Bhagwan” means the 24 Tirthankars of our present half‑time cycle (Avasarpini). The 24th is Bhagwan Mahavira.

• If you meant “before the 24th Bhagwan”: that is the 23rd Tirthankar, Bhagwan Parshvanath.
• If you meant “before this set of 24”: every half‑cycle has its own set of 24. Before our present set, there was an earlier “chauvisi” in the previous half‑cycle, but the names of that earlier set are not the focus of present tradition.
• “Next 24th Bhagwan”: in this current Avasarpini there will be no more Tirthankars after Mahavira. The next set of 24 Tirthankars will arise in the next half‑cycle (Utsarpini). Their individual names are not detailed in commonly followed scriptures.

Digambar–Shvetambar note

• Both traditions fully agree there are exactly 24 Tirthankars per half‑cycle, ending with Mahavira in this one. They differ only in some historical details (e.g., Mallinath’s gender, parents’ names, emblems), not in the count or the doctrine.
