Can we have multiple instance of a Service in Android ?

No. You can have multiple subclasses of Service, but any given subclass of Service will have precisely 0 or 1 instances at any given moment.

I want a service which can make phone silent on a specific time and I want to re use that service to make the phone in vibrate mode in specific time.

You should not be using a service for any of that. Use AlarmManager and a BroadcastReceiver, please.
