CH3Cl>CH3F>CH3Br>CH3I
 
This is because Cl being large atom has large bond length and hence the contribution of length here dominates as dipole moment is the product of the charge and the distances b/w them.
And for rest atoms the factor remains the electronegativity.
 
In second,
the order is:
CCl4
as CCl4 is totally non polar as two Cl atoms cancel each other’s dipole hence.
in CHCl3 three atoms of Cl cancel each other’s olarit and produces small dipole and in CH3Cl all the atoms adds up the dipoles.
