For information on the standard badges, see the Badges Wiki. As for custom edit tracks (which aren't documented well on that wiki), the counts are 1, 5, 10, 25, 50, 100, 250, and 500. I believe the 500 count badge is re-obtainable every 500 edits. In other words, a user earns another one at 1000, 1500, 2000, 2500, etc. This effectively gives the edit track an infinite number of badges; although there are only 8 different designs that can be customized.
