Here is a table that lists the pKa for organic and inorganic compounds.

For example, H2O is 15.7 and HF is 3.17. That means HF is a stronger acid than H2O. I couldn't find NH3 in that list but it is 9.25. Be sure you look in the water column and not the DMSO (dimethylsulfoxide) column for the right solvent.
Rank the given compounds based on their relative Brønsted acidities.
H-CH3
H-OH
H-Cl
H-F
H-NH2
