Proximity sensor not working is probably due to the screen not being put on properly. Either there is too much gap between the glass and the front display housing frame itself or some adhesive is actually obstruction the proximity sensor.
As for LED notification I think that is part of the headphone jack assembly if it's next to that and they probably didn't bother putting the notification LED plastic piece that focuses the LED with the white (opaque) plastic piece.
Fingerprint scanner is on the power button right? If yes they probably damaged it because it sounds like they gave you a whole new screen with a frame.

You should probably take it back to where you got it repaired from and talk to them about this.
