I need immediate email notifications, how to change that interval time ......

When some host is down or any other issue, i need immediate notification

You would need to change your max_check_attempts to 1:

max_check_attempts: This directive is used to define the number of times that Nagios will retry the service check command if it returns any state other than an OK state. Setting this value to 1 will cause Nagios to generate an alert without retrying the service check again.

And you may in turn, want to change your retry_interval as well:

retry_interval: This directive is used to define the number of "time units" to wait before scheduling a re-check of the service. Services are rescheduled at the retry interval when they have changed to a non-OK state. Once the service has been retried max_check_attempts times without a change in its status, it will revert to being scheduled at its "normal" rate as defined by the check_interval value. Unless you've changed the interval_length directive from the default value of 60, this number will mean minutes. More information on this value can be found in the check scheduling documentation.

In which file i need to edit this.

You would need to change this in the service or host.cfg files which you want to alter. On a Centos/Rhel installation the path should be:

Am not able to find that file in Centos 5.6

That is the path to the configuration files of your hosts and services.

It seems like you may want to do a bit of reading on Object definitions as all of the questions you have had were answered through these pages here:

sometime i will get notification for some printer and if sometime I'll not get notification even the host is down also.

Is the host in a HARD down state, or just a soft? Was it flapping?
