I think of it as more of a probability question. There is a much greater chance of a person having two copies of chromosome 21 instead of three. "Normal" often carries some form of judgement but I guess technically you are correct to use the word.

No. Having two copies of each chromosome is NORMAL. Having 3 is NOT normal. Being completely unwilling to make normative statements seems rather cowardly.
