I have done this but friends icon is not at front.

You can notification and messenger icon by using import menu item option. Then you need to disable notification and member icon from old place. Then you can see the notification counter.

As for example you can see at publicapp.in 

I have not added friends icon because that have two friends menu item first one for persons and second one for organisation so both icon are being visible. So I have not added friends icon.

I hope you understand my language or if not then I will add comment to do that with step by step.
