Hello,
there is no routing configured (static or dynamic) between your routers. Also, the IP addresses of the hosts on the left are not in the same subnet as the default gateway. In order to facilitate the assignment of the correct IP addresses, I configured DHCP pools on both routers, and enabled DHCP on the first ten clients from the top down. You need to enable DHCP on all clients. I also added EIGRP as a routing protocol. You could use RIPv2 or OSPF as well.
Attached the revised file.
