Size:  129.2 KB shouldn't these three protons be in the same environment? as each of them has two neighbouring proton

    No.

    The environment depends on all of the atoms in the molecule. The para (4) position is more bonds removed from the OH group than the meta (3,5) positions.

    Your mistake is very common in NMR. You should consider environment in terms of holistic position and symmetry.

    How to know which position has more bonds removed?

    I mean "number of bonds distance from"
