In Jain cosmology, there are seven Narakas (hells) in the lower world. From top to bottom, their common names and brief sense (arth) are:

• Ratna-prabhā: ground studded with jewels; the least severe of the seven.
• Śaṛkara-prabhā: ground of gravel; somewhat more painful than Ratna-prabhā.
• Vālukā-prabhā: ground of hot sand; more intense suffering.
• Paṅka-prabhā (Panka-prabha): ground like mud or filth; harsher torments.
• Dhuma-prabhā: ground filled with smoke and burning heat.
• Tamaḥ-prabhā: deep darkness and severe torture.
• Mahā-tamaḥ-prabhā: the deepest, most intense of the seven.

These seven Narakas are acknowledged across Śvetāmbara and Digambara traditions, though exact phrasing or minor details may vary between texts. After karmas exhaust, beings may be reborn in higher realms; the Narakas themselves are not eternal. You can read more here and here .

If you want, I can list the causal factors (papa-sthana) that lead to Naraka births as well.
