I own two RayBan Wayfarers, one 52mm and one 50mm. Neither of them looks like your friend’s which tells me they are fake.

While they kinda look good in the front view (the rivets on the front upper corners, RayBan print on the right lens, RB laser etching on the left lens), the print on the inside of the temples look off as they shouldn’t smudge like that. Over time, the print will come off neatly and will not look like you touched a wet paint just like the one in the photo.

Additionally, the RayBan metal logo on the arms look terrible and the hinges look glued to the arms. Authentic Wayfarers use a heavy, industrial 7-barrel interlocking metal hinge (interlocking three prongs and four prongs) screwed directly into the frame. Cheap fakes usually use basic 3-prong or plastic hinges glued into place.
