They're witches, just not. At all. Stop using such derogatory names. The proper word is Conjurers. They come in covens, and, in the coven Vanellope's in (and the youngest of) there is: Merida, a caster; Elsa, a cyrokinesis; Rapunzel, a healer; and Astrid; an enhanced. And of course, there's Vanellope, a dimension shifter (fancy name was what it really is; she just stops time).
Just one itsy, bitsy problem (other than constantly being in intimate danger); Vanellope went careless and got caught by super genius about to get his perspective on life reworked.
