ok so we get this question almost everyday . the problem is that there are over a million apps each with their own notification icons. so unless it is something like facebook or youtube, you will only get guesses from us.
the only true way to know is to look in the phone's notifications by pulling the notification bar down or thru the phone's settings. so you will have to ask this "someone" to do this. or have this "someone" ask their significant other what the icons are.
i would not hold your breath here for too long expecting an answer.
