Are these app icons or notifications?
The one on the right just looks like a clock notification: possibly an upcoming alarm? But there seems to be some theme applied to the phone, and if that changes the appearance of icons it's even less likely that anyone will be able to say for sure (there are literally millions of apps out there, so most of these questions go unanswered).
Frankly you need to forget about identifying things on her phone and sort your relationship out, one way or another. That's where the real problem is, and winding yourself up because you don't recognise something on her phone isn't going to help with that (think about it: if someone is able to say "these are nothing" will you stop worrying, or just go crazy the next time you see something unfamiliar? If someone says "that could be something you'd not like" what are you going to do? And if she finds out you've been photographing her phone screen and asking the internet what's on it how is she going to react? I don't see how any of this will help with your real problem).
