Call it K, so K contains Q, and |Q| < |K| < c=|R|. OK.

Yes. Almost all the K aren't Q, and almost all the R aren't K.

Yes.

Correct.

Non-sequitur. The purpose of intuition is to guide you in developing proofs or solving problems. Feel free to use your own intuition and reject that of others. If you're not going to be proving theorems or solving problems, there's nothing wrong with having an intuition at odds with everyone else's.
However, as a data point, the intuition that's developed over the last two centuries or so, the one you reject, seems to work in proving theorems and solving problems.
The concepts of infinity contain much that seems contradictory. Intuitions based on your finite world simply don't work. The best way to develop new ones is to work with these things, or to accept the visualisations that others provide.
