Although serger feet are matched to their machines according to the brand and model number, they can be interchanged. In other words, you might be able to use a serger foot for one machine brand with another machine.
The shank type is determined by the length between the serger foot and the serger foot screw. This length is measured when the serger foot lever is down.
If you have a low shank model of any of these brands, you can interchange their low-shank serger foot. The same goes for the high shank models.
