especially, this configuration is for loadbalancing, let's make Multiple HSRP.
★ Instructions
1. Make Switches L2 mode.
2. Switch1-1 and Siwtch1-2 are same device.
3. Set NAT at Router1
4. Set HSRP at Router 2,3. Router2 is active router at HSRP1. Router3 is active router at HSRP2.
5. 2 virtual router are running as PC1 and PC2
6. Vlan100 is assigned both interface at Switch1. Vlan200 is assigned between Router 1,2,3.
Vlan30 is assigned Router 2,3,4,5.
★ Configure is like this.

★ Outcomes
1. Using traceroute command, check the route.
route is correctly good.
2. You can check NAT translation using 'show ip nat translations' command.
3. also you can check two HSRP status using 'show standby brief' command.
