Multiple notification status

First issue is ;

For example , francis sent a message to emre and the notification came, then claire sent a message to emre but claire's notification replace to francis' notification. I want two different notifications to appear.

Second issue is ;

When network connection is off, claire sent 5 message to emre. When emre connected to network , emre takes 5 notification. But I would like to make just take 1 notification.
