Answer 1

Try to stop nginx, start varnish, start nginx.
You can see which process is listening on the port with the commandlsof -i tcp:80

Answer 2

First, it is worth figuring out what and on which port you want to hang.
If Nginx is on 8080, then .port = "8080" should be written in /etc/varnish/default.vcl - this is the backend setting, that is, what Varnish will access for content, and not the port Varnish listens to. The latter in Centos 7 can be configured in /etc/varnish/varnish.params and in the systemd service file.
