You can't listen to same port with two servers but if you want you can configure Nginx as a reverse proxy for apache. Here is a great tutorial to do that https://www.digitalocean.com/community/tutorials/how-to-configure-nginx-as-a-reverse-proxy-for-apache. You can also check this one http://kbeezie.com/apache-with-nginx/ .
Hope this might help you.
As it has already been stated above, it is impossible to run different services on the same port as only one service can run on a port at a time. You can however run Nginx as a proxy server (each one running on a different port).
Note: you can configure each server's document root to load different home pages when both are running on different port (if that is what you want).
