Can You Name The Character or Role From The Actors/Actresses Who Played It? 

I missed only 6. I'm impresssed you were able to find so many characters portrayed by three or four different actors.

It's a little unfair to include Lady Gaga as Harley Quinn. She's going to portray the character in the sequel to the Joaquin Phonenix Joker movie, but that won't even be relased until 2024. You should have used Arleen Sorkin, who voiced her in THIRTEEN TV series and video games.
