Haven't downloaded the resource myself, but it looks like they were made using RPG Maker MV's character generator.
Characters from the RPG Maker MV character generator can definitely be used in RPG Maker MZ (I do it all the time, I even prefer MV's generator over MZ's).
But legally speaking, I think you need to own RPG Maker MV in order to use any resources created from its art assets, and are usually only allowed to use RPG Maker assets for RPG Maker games.
I know you posted this like a year ago, but I figured I'd leave my answer here for any other internet denizens that come by.
