I have 3 different Date objects and I want to pass them to AlarmManager object to alert me when they occur.

May I need to use 

 Calendar cal = Calendar.getInstance();
         cal.add(Calendar.MINUTE, 2);

to add 2 minutes to the calender, but how to add a future date object to the calender ?

Do I need A Calender object, or I need a separate Calender object for each Date ? Them for AralamManger do I need one object to 3 ?

I will advice you to use three different Calendar objects in which future dates will be set as below:

Calendar calendar1 = Calendar.getInstance();
            Date future_date=new Date();
             future_date.setHours(hour);
                future_date.setMinutes(min);
                future_date.set(year, month, day);
                calendar1.setTime(future_date);

....OR.......
calendar1.set(year, month, day, hourOfDay, minute)
