How do I count hydrogen bonds?

A hydrogen bond is any bond between H and F, O, or N. You can count the hydrogen bonding sites for these.

Hydrogen bonds are a bond between hydrogen and either O,F,N. Potential hydrogen bonding sites are a lone pair on an O,F,N atom binded to an H, or H binded to O,F,N.

You can also look at the number of lone pairs on N,O or F atoms

Lone pairs on O, F, or N can form hydrogen bonds with a H that is connected to an O, F, or N.

A hydrogen bond is between a H and an N, O, and F. Potential bonding sites are on the lone pairs of N, O, and F.

Like, everyone else has mentioned a hydrogen bond occurs when a highly electronegative N, O, or F atom shares a lone pair of electrons with an electron-deficient H atom. O---H---O for example, like #14 on Sapling.

It has to be hydrogen paired with (of course itself), or F, O, or N

Hydrogen bonding occurs between an attraction of a hydrogen atom to an electronegative atom like N, O, or F. H atoms will be "automatically" attracted to these atoms in other molecules.

You count hydrogen bonds by counting the amount of bonds you see between H and the elements F, O, and N.
