All kata ask for more or less the same thing, basically differ only w.r.t. allowed alphabet of a password.

Kata 2. asks for actual regex, which is the only one which forced me to use regular expressions. I think it's good to keep.

As for remaining ones, I don't know which one would be the most interesting to keep. Are special characters in 4. any interesting? Does input being a list in 5. make the task any better? I do not have any favorite here.

I suggest to keep 2 only and retire the rest as there are already many validation katas available with / without enforcement of regular expressions !

I like 3 the most. 2 has several problems: it is overranked, its shell translation is different from other languages (it is similar to other katas where regex is not required). But I think it is fine to keep 2 and fix the shell translation. I would also like to keep 3.

I would keep 2 (because of the regex requirement) and 3 (clear description, most completions).

keep 2 and 3 and retire the others sounds fine to me
