“Bahu Swami” is not one of the 24 Tirthankars of our Bharat Kshetra (like Rishabhdev, Parshvanath, Mahavir Swami, etc.).

In Jain scriptures, Shri Bahu Swami is known as one of the 20 present Tirthankars in Mahāvideh Kshetra (a special, pure region of the universe where Tirthankars are always living and preaching).

So, in short:

• In our world-region (Bharat Kshetra) and present time-cycle: there are only the well‑known 24 Tirthankars, ending with Bhagwan Mahavir. No Bahu Swami here.
• In Mahāvideh Kshetra: among the currently living Tirthankars, one of them is Shri Bahu Swami, along with others like Shri Simandhar Swami, Shri Yugmandhar Swami, Shri Subahu Swami, etc.

If you were asking whether “Bahu Swami Tirthankar” is from the usual 24 we worship in temples here – the answer is no; he belongs to the group of Mahāvideh Kshetra Tirthankars, accepted in Jain cosmology.
