The top left prongs are for the GPS antenna, the top right prongs are for the NFC antenna and the prongs near the battery terminal are for the WI-FI antenna, if any of them are broken off it will most likely break the loop on the terminal pads which is needed to transmit the signal through one prong into the black antenna pads located inside the lid and back through the mobo circuit.
Im unsure of the purpose of U62 as it does not contact any terminal pads inside the lid but might have been placed there as is the large square hole in the chassis just above the battery for later modifications like adding a rear camera.
I hope this helps and if a prong is missing you can most likely find one similar in a laptop or scrap tablet and solder it on as a substitute.
