No they do not all fit. My suggestion would be to take your pandora braclet and test them first. My sister in law bought some last spring and they did not all fit. She in fact broke a Murano glass charm trying to force it onto her Pandora bracelet.
As noted above, Chamilia does have Disney charms, I have Mickey and Minnie and they are adorable. They have a good selection of everything from Disney quotes to dalamations and Winnie the Pooh. Pandora does have a non-Disney slipper, pumpkin carriage and castle. I have the pumpkin carriage and it is so cute. It has a pearl at the top.
