In Jain Dharma, the main two samuday (traditions) are:

1. Digambar
2. Shwetambar

Within these, there are also many sub-sects or gacchas/sampradayas, such as:

• Sthanakvasi
• Terapanthi
• Murtipujak

So, if you mean the main samuday, the answer is 2. If you mean all sub-groups, then there are many.
