Can't deploy two apps in Nginx - nginx

Question

I developed an application using Django(rest-api) and reactJs with webpacker. It is working in local. Now I need to deploy it in an nginx server.
I have ssh access to nginx server(lets say server name: vardhan.com and username: vishnu). Can someone help with how to do it.
I am following this tutorial. https://tonyteaches.tech/django-nginx-uwsgi-tutorial/
But I got few questions.
There is already a survey application running in the same server and it can be accessed with url vardhan.com/survey. is website address(url) same as server name ?
How to host two applications in the same sever ?
This is .conf of survey app
