If you have 3 different sprite objects, just combine their conditions in the event:
+ Sprite1 Angle 0?
+ Sprite2 Angle 0?
+ Sprite3 Angle 0?
-> Do whatever
If you have 3 instances of the same sprite, your could create a global (e.g 'anglesMatch') and then do
+ Always
-> System 'anglesMatch' = 0
+ For each Sprite
++ Sprite Angle 0?
--> System add 1 to 'anglesMatch'
+ 'anglesMatch' = 3
-> Do whatever
Edit: Note that this doesn't pick the instances.
