Hi ajay_kumar,
What do you mean by :
"The VPN Tunnel is UP and LAN to LAN comminication is working without any problem. However I'm unable to access / ping any devices in 192.168.5.0/24 from SRX Box."
Do you mean you can ping from any PC on your LAN ( 192.168.41.0/24 ) to the remote LAN 192.168.5.0/24 except from the SRX ?
Your Obscufication of the IPs using the same annotation ( Y.Y.Y.Y ) makes the logs you posted almost useless, can you post the configuration please ?
