Intermediate filaments can indeed be composed of various proteins, including vimentin, which is common in cells of mesenchymal origin. They are not 7 nm in diameter (that's the diameter of actin filaments), they are not abundant in plant cells (which primarily rely on microtubules and actin filaments), and they are not the only cytoskeletal filaments responsible for animal cell shape (microtubules and actin filaments also play crucial roles).
