How can you tell how many hydrogen bonding sites there are?

Each lone pair on an oxygen, nitrogen, or fluorine is a potential hydrogen bonding site and each hydrogen that is attached to an oxygen, nitrogen, or fluorine is a potential hydrogen bonding site. For example, water has 4 hydrogen bonding sites (2 lone pairs on oxygen and 2 hydrogens attached to the oxygen).

Each lone pair on an oxygen, nitrogen, or fluorine is a potential hydrogen bonding site. Also, a hydrogen that is attached to an oxygen, nitrogen, or fluorine is also a potential hydrogen bonding site.

In organic molecules where they don't show the carbon atoms or lone pairs, do we assume that there are lone pairs around Oxygens or hydrogens...?

You would assume that each atom has however many lone pairs it would need for a complete octet

Each hydrogen that is attached to either N, O, or F counts as a potential binding site and every lone pair on a N, O, or F atom

as long as one molecule has O,N,or F it is a potential bonding site as long as there is a Hydrogen on the other molecule

hydrogen bonding sites occur at lone pairs and at hydrogens that are bonded to O N or F (forming a polar hydrogen bond)

Any hydrogen attached to a F, O , or N , and any lone pairs on those atoms can make hydrogen bonds.
