Hi Saurabh

I assume by "one charm instance to another" you mean two units in the
same service?

In which case, having the charm implement the peer relation would
allow that communication. E.g. if one unit does a relation-set
password=<secret>, all other units (instances) in the service will be
able to do "relation-get password" in the peer relation-changed hook.

If you mean between two instances of different charms, then a normal
relation will do, of course,
