I have a very long response to it, but it ultimately boils down to telling you that API = the type of AACI called by your equipment setups.

And the abbreviations have the explanations next to them, i.e. try reading the table like this:

as "Type 1 AACI (for Akizuki-class DDs only), requires 2 High-angle Gun Mount (e.g. 10cm Twin High-angle Gun Mount + Anti-Aircraft Fire Director) and an air radar (e.g. Type 13 Air RADAR Kai) to trigger at a rate of 67%. This AACI shoots down up to 7 planes per slots it is assigned with."

I might be wrong but this is how I read it.

As for the other abbreviations, there are ones like

M = main guns (for battleship AACI)

S = Type 3 Shell (for battleship AACI)

A = Anti Aircraft Fire Director

C = 25mm Triple Autocannon Mount (Concentrated Deployment)

TL;DR - Try to understand the notes.
