Slot upgrades are the most involved icons.

The way they work is Template:SlotUpgrade uses the generic Template:PercentBar to generate a sequence of on/off indicators indicating a discrete percent (in this case 1 or 2 out of 2).

You will need to create a file at and  to make the Zero one, and the same for "Ao" too. They must be a single "pip", so the way I did it before was to image edit two halves of a pip together, one from each outside of the "on" state and the same with the "off" state. Or in Akatsuki's case, they were already separate. Then there must be 2px of transparency on the left and right of the image and none on the top and the bottom. This has to do with overlap and should allow for the Ao variant to overlap correctly if it has semi-transparent edges like it appears to.

Based on doing this myself with the icons you've linked (that don't have transparency), the result should be 14x26 for Zero (10x26 without transparent padding) and 18x33 for Ao (14x33 without transparent padding).

It was made this way for Akatsuki first. Then when I found out about how Cold Steel does it (and how Cold Steel does Template:StarRating), so sorry if that's more complicated than Template:Quartz was.
