In Jainism, there are a total of 24 Tirthankaras (spiritual teachers who have achieved liberation and show the path to others). If you are referring to the first four Tirthankaras, they are:

1. Rishabhanatha (Adinatha) – The first Tirthankara.
2. Ajitanatha – The second Tirthankara.
3. Sambhavanatha – The third Tirthankara.
4. Abhinandananatha – The fourth Tirthankara.

Each Tirthankara played a significant role in reviving and teaching the Jain Dharma.
