The order of increasing polarity in HCI , CO2,H2O, and HF molecules is:

The geometry of CO2 molecule is linear so the dipole moment of two C-O bonds cancels each other because of opposite directions and CO2 becomes non-polar. In other molecules, order of electronegativity of Cl, O, and F is Cl < O < F. So polarity order is H-F > H-O > H-Cl bonds.
