Monster-Paparazzi-Bad romance-Telephone- on piano?

So anyone of these would be good, preferably the first two, i've found the chords on paino for paparazzi but is completely impossible for me since i haven't played since i was young....i'm wondering if anyone can help me please! find either the sheet of music (free without downloading) or some notes or something! i love her to death and my sis wants to learn soo...thanks so much! i've looked at most of the videos but if you find one that you think would actually help, that's fine too! thanks^^
