The decreasing order of Acidic Strength (most acidic to least acidic) is :-
o-toluic acid > benzoic acid > p-toluic acid > m-toluic acid.

O-toluic is most acidic due to Ortho effect.
p-Toluic acis is less acidic than Benzoic Acid because of the +I effect of the Methyl group which will destabilize the conjugate base of p-Toluic Acid.
Similarly for m-Toluic acid is least because Methyl is at meta position.
