Acidity means ability to readily give H+ ions.
The order of the most acidic will be
HI > HBr > HCl > HF
Since H is a small atom, and I is a big atom, so it would be easy for them to break the bond, hence H+ ions are most readily given.. While H and F are small atom, so they have a strong bond between them (high bond enthalpy).. and so, they would be least acidic.
