I have  a couple of guesses:

Obviously they are

Gothel

Anastasia

The other six I'm guessing

1.       Madam Mim

2.       Madame Leota from the Haunted Mansion

3.       Yzma

4.       And the Three sanderson witches

I also thought Alice could be a potential one, being Gothel's daughter and everything,  but I don't recall her ever using magical abilities. But hopefully, they'll stray away from a parent trying to convince their child to join the dark side (don't want another Vader/Luke scenario to happen)
