Answer:
0,0,0,0
Explanation:
The formal charge formula:

So:
Hydrogen: 1 elec. of valence and shares two electrons with the O

Oxygen: 6 elec. of valence, 2 lone pairs and shares two electrons with the H and two with the F

Fluorine: 7 elec. of valence, 6 lone pairs and shares two electrons with the O

Oxygen: 6 elec. of valence, 3 lone pairs

Note: the dative bond between F and the second O doesn't count as shared electrons.
