left is standard scuba inflator
middle looks like the automotive quick connect which is used for air guns and what not, so is the one on the right it appears, but could also be the Air2 type fittings, don't pay enough attention to ID them from pictures.
There is also an industrial coupling that has a bigger flare on the top of it, and automotive type that looks very similar to the ones on the right that you linked, an ARO type, and a "universal" type for the air tools.
Omniswivel and Swagelok also have their own for QC4/QC6 and others. Whole bunch of different types of quick connects for bc's, especially those that have Air2 type inflator combos on them. Unfortunately way too many, but most of the scuba industry uses the quick connect you posted on the left for everything except breathing lines
