11. Merida: Kelly Macdonald
I can't see many similarities between the two, but to be fair she was animated by Pixar and not Disney. They both seem like strong independent women though :). And I found a picture where they have similar hair!
12. Anna: Kristen Bell
I can see similarities in face shape. Also their eyes are both curvy. I have to admit that Kristen looks more like the original concept to the actual one. I Believe it was changed possibly to the complaints of fans that she looked too much like Rapunzel.
13. Elsa: Idina Menzel
They both have the same cheekbones, and eye shape. Their noses are pointy and their faces are long, though Idina's is more so. I believe Elsa would've had brown hair like Idina's if she didn't have powers because her eyebrows seem to be a chesnut brown color. Their lips are long horizontally. Idina Menzel has played multiple characters similar to Elsa before, most notably Elphaba in Wicked.
