Nobody has fallen in love with Orihime so far and we cannot possibly know what will happen in the future of the story - only the author knows such things.
Orihime, on the other hand, has expressed her love of Ichigo Kurosaki. The only other person who knows about Orihime's love for Ichigo is Rangiku Matsumoto. Orihime has not expressed any romantic interest in any other character.
Actually, more towards the begining of the series Uyruu showed a slight interest in Orihime. Back when they got seperated from everybody else when they went to the Soul Society to save Rukia. But that died away as they dwelved further into the story.
I don't think Uryu's feelings have "died away" at all. We don't know if he's in love with Orihime, but he certainly has a soft spot for her. He also seems to understand her rather well.
