you can use a virtual host in Apache to respond to name based requests. If no hostname matches, such as when you use IPs, it's just the first one loaded from the config files, in the order they are configured.

I am writing all the configuration under /etc/httpd/conf.d/

in this is case how it will identify which one as 1st configuration ?

As above it's the first one loaded in order.

Apache identifies requests for virtual hosts based on their names. Have a look at the sample httpd-vhosts.conf:

Code:

NameVirtualHost *:80

<VirtualHost *:80>
    ServerAdmin webmaster@dummy-host.example.com
    DocumentRoot "/usr/docs/dummy-host.example.com"
    ServerName dummy-host.example.com
    ServerAlias www.dummy-host.example.com
    ErrorLog "/var/log/httpd/dummy-host.example.com-error_log"
    CustomLog "/var/log/httpd/dummy-host.example.com-access_log" common
</VirtualHost>

<VirtualHost *:80>
    ServerAdmin webmaster@dummy-host2.example.com
    DocumentRoot "/usr/docs/dummy-host2.example.com"
    ServerName dummy-host2.example.com
    ErrorLog "/var/log/httpd/dummy-host2.example.com-error_log"
    CustomLog "/var/log/httpd/dummy-host2.example.com-access_log" common
</VirtualHost>

When the machine has one IP, apache uses the ServerName directive to identify which virtual host is being requested. You can read all about it in the Apache Virtual Host documentation.
