lone pair delocalized so less basic than aniline. Solution

-M effect of -NO2 decrease the basicity so it is less basic than aniline. Solution

-CH3 group at ortho so ortho effect exert here hence basic character decrease as compare to aniline. Solution

Lone pair of -N involve in delocalization and ring become aromatic due to this so it is also less basic then aniline. NH3 is more basic then aniline because phenyl group exert -I effect. (.v.) is derivative of guanidine so they are more basic than aniline.
