In Jain cosmology, the Devalok (heavenly realms) count is not fixed to a single number. Depending on the tradition:

• Digambar sources typically enumerate 12 Devaloks.
• Svetambar sources often enumerate 16 Devaloks.

Thus, the total Devalok count is 12 or 16, with the upper worlds housing the Devas (gods) and the lower/middle worlds containing humans and other beings. ( jainqq.org, slideplayer.com)
