lowest pka will be for  amonium action   since its more acidic .    because. you know  NH2 is base    C=_C H is only slightly acidic  and you know .OH  is aliphatic is less acidic than water 
  but   since.  NH2 is weak base comparetively   pls 10.2 .     NH3+. will have pka 3.8 . so its highly acidic than others
