Hey angel lover
Don't worry about asking questions!! We all had to learn this stuff at some point. The important thing is that you're finding out.
If someone mentioned an airstone, they mean one of those (usually blue) porous little stones that you attach to the end of some airline tubing, powered by a small air pump. They blow tons of tiny air bubbles in a current to the top of the tank. Some people add them just because they like the look of the bubbles, but their purpose is to increase surface agitation and facilitate gas exchange via popping bubbles, effectively increasing the oxygen level in the water. However, water has a maximum oxygen carrying capacity, and most power filters nowadays create enough surface movement to provide adequate oxygen for the fish. Plus, I seem to recall that you added live plants a while back; these will also aid in oxygenating your water.
Added filtration essentially means providing extra filter media for more nitrifying bacteria to colonize. Is your filter a hang on back waterfall style one? If so, do you use some sort of all in one cartridge or bags in it? I would highly recommend that you stuff filter floss in the filter chamber. It's excellent for housing bacteria and is a good mechanical filter too, catching most particles that pass through. However, if you're going to keep that many angels in a 55, I'd recommend that you also add a second filter (stuff that one full of floss, too).
Hope that helps somewhat.
