Here is a very short Jain cosmology kshetra breakdown:

| Kshetra / Region | Main breakdown | |---|---| | Urdhva Loka | Devaloka and higher celestial realms | | Madhya Loka | Manushya-loka and Tiryanch-loka (middle world) | | Adho Loka | Naraka realms (infernal worlds) | | Siddha Kshetra | At the top of the Lokakasha, abode of liberated souls |

Broad internal division of Loka:

• 1 Adho Loka
• 1 Madhya Loka
• 1 Urdhva Loka
• Above all: Siddhashila / Siddha Kshetra

If you want, I can also make this into a 14 rajju-style Jain cosmology table.
