The bond angle in \mathrm{NF}_3 is the smallest because the lone pair in \mathrm{NF}_3 is more electronegative and repels the bonding pairs more strongly than the lone pairs in the other molecules. This causes the bond angle in \mathrm{NF}_3 to be smaller than the bond angles in the other molecules.
