In Jainism, there are seven Narakas (hells) in the lower world (Adho Loka).

The seven Naraka grounds are:

• Ratna-prabha
• Sharkara-prabha
• Valuka-prabha
• Pankā-prabha
• Dhumā-prabha
• Tamaḥ-prabha
• Mahā-tamaḥ-prabha

These are described as the seven successive hells where beings suffer for their karma before taking a future rebirth. You can read more here .
