nginx: [alert] mmap(MAP_ANON|MAP_SHARED, 134217728) failed (12: Cannot allocate memory)
nginx: configuration file /etc/nginx/nginx.conf test failed

I'm using amazon lightsail 5$ plan thanks
That, unfortunately, may be the issue - it seems that you're out of available RAM.
That being said, you may also have a bad Nginx configuration - run sudo nginx -t or check the /var/log/nginx/error.log to see more details on what it says.
Yes buy another plan for that customer, isn't customer paying for plan anyway?
no i'm using for my startup and now i don't have any customer so i thought first go for 5$ plan and after if i got customer then i'll migrate for bigger plan(money problem), i have question is that its fine to deploy two app one for demo and one main app? thanks
A couple is fine, but like @fideloper said, ram can be an issue.
You should be alright once you get a paying customer, meanwhile use your plan for testing.
For test you could probably have more, but only use one or two at most at a time.
i restart my server and everything looks fine but when i try to visit demo.mysite.com its not showing page and errors "demo.mysite.com server dns address could not be found DNS_PROBE_FINSIHED_NXDOMAIN"
you may also have a bad Nginx configuration
what is the best Nginx configuration for multiple app , any reference thanks
I meant there may have been an error (syntax error usually) in the configuration. The command sudo nginx -t will show you if there is.
There isn't really a best Nginx configuration to help with this particular issue.
