No, it does not fit, I still have one from the Note 10 that fits, but no connection can be made, as with the S23 Pen as well.

Unfortunately only for S23 Ultra, according to the description.

I suppose so, I can't really judge it as I only own the S23!

The galaxy s23 ultra and 22 ultra are relatively similar in size and software, I think it should actually work.
