I'd recommend to take a look on how it's organized in www/nginx-devel [1]
in FreeBSD ports tree [2].  The management script [3] of that port
supports profiles, so it's possible to run several instances of nginx on
the same box.

1. Enable nginx in /etc/rc.conf:
nginx_enable="YES"

2. Specify needful profiles in /etc/rc.conf, i.e.
nginx_profiles="1 2 3 4 5"

3. Add lines with configuration files:
nginx_1_configfile="/usr/local/etc/nginx/nginx.conf.1"
nginx_2_configfile="/usr/local/etc/nginx/nginx.conf.2"
nginx_3_configfile="/usr/local/etc/nginx/nginx.conf.3"
nginx_4_configfile="/usr/local/etc/nginx/nginx.conf.4"
nginx_5_configfile="/usr/local/etc/nginx/nginx.conf.5"

4. Here's an example of the /usr/local/etc/nginx/nginx.conf.1 file:

worker_processes  1;

error_log  /var/log/nginx-error.log  debug;

events {
    worker_connections  10240;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    keepalive_timeout  65;
    include /usr/local/etc/nginx/conf.d.1/http_*.conf;
}
