My suggestion:
Judas -> it would work kind of as an intro. The verses of these kind of songs never sound impressive so I would just do chorus (i'm just a holy fool...) + post-chorus (ooh i'm in love with Judas) + outro (Judas juda-ah)
Alejandro -> violin intro+ verse+ postchorus (extended like in the video)
Paparazzi -> while Alejandro's post-chorus, the instrumental for the song starts to build up. Also shortened
Applause - Also Shortened
Rain On Me -> Ariana appears
Into You
ARUTW -> piano moment similar to MR in 2917
Shallow (rock version) epic finale
