Not sure about the others, but I downloaded the Lucario one, and as you can see from the .material file, it is set to be preset 1.
So, just copy all the files, and paste them into
C:\FeralHeart\media\my_presets\preset_1
Once you've done that, you'll need to restart FH, and then head to Preset Maker.
Click Preset 1, then export.
Exactly what Ruby said. When you export it, you must click replace.
