No.

In Jainism, two souls are not absolutely forbidden from meeting in heaven. Their meeting depends on their karmas and rebirth, not on a permanent rule forbidding contact.

A soul that has committed wrong actions, including repeated indulgence in sensual or impure content, may bind bad karma and be born in a lower or different state. But that does not create an eternal ban on meeting another soul in heaven.

So the strict Jain answer is: No, not forbidden absolutely.
