In Jainism, devas can interact with one another and, in some cases, with beings in the human realm.

A few simple points:

• Devas are not liberated souls; they are still within the cycle of birth and death.
• They may communicate, सभा-करण, or meet within their own celestial realms.
• Some devas may appear before humans or influence events, but this is not the same as liberation.
• Their interaction depends on their type, realm, and karmic अवस्था.

If you meant a specific class like Kalpavasi Devas or Kalpopapanna Devas, then the answer is also generally yes, within their own celestial system they can interact, but their abilities and reach vary by category.

If you want, I can explain the different types of devas in Jain cosmology in simple words.
