Answer

In Jain cosmology, the heavenly worlds are called Devlok. They are situated in the Urdhva Lok above Madhya Lok.

The distances are traditionally described in very large Jain units such as Rajju, Yojan, and Sagaropam-related cosmological measures. Exact measurements vary by the way different Jain cosmology texts explain the structure, so it is important not to casually convert them into modern kilometers or miles.

Main Devlok Classification

The heavenly realms are generally described in four broad categories:

• Bhavanvasi Dev – residential gods, located in lower regions near the middle/lower universe.
• Vyantar Dev – wandering gods, associated with mountains, forests, and atmospheric regions.
• Jyotish Dev – luminous gods, connected with sun, moon, planets, stars, etc.
• Vaimanik Dev – celestial gods living in higher heavenly vimānas.

Among Vaimanik heavens, the commonly mentioned heavens include:

• Saudharma
• Ishana
• Sanatkumara
• Mahendra
• Brahma
• Lantaka
• Maha Shukra
• Sahasrara
• Anata
• Pranata
• Arana
• Achyuta

Above these are the Graiveyak, Anuttar, and then the highest liberated realm called Siddhashila, where liberated souls reside.

Important Note

Sorry, I can only provide information that is clearly established within Jain tradition. I should not give a numerical “distance of each Devlok” unless the exact traditional table and unit system being used is clear.

Takeaway

In Jain Dharma, the purpose of learning about Devlok is not merely geography, but to understand that even heavenly pleasure is temporary. The final goal is not Devlok, but Moksha at Siddhashila.
