could this two session can tell  us does firewall receive reply from c.c.c.c , does the firewall forward packet from c.c.c.c to outgoing interface . if cannot confirm with this two session. how can i confirm those information 

The session view does not have any byte counters to tell if there is actually traffic in either direction.

But if you use the web interface and go to the polices view.  Turn on logging for the policy.

In the policy logs, there is a byte counter for both ingress and egress for each session that gets logged.
