This is actually a pretty decent list.

For the password requirements, I would actually always show them as a list of bullet points (length, casing, special character, number, no name…) which would validate on change, from a list of red crosses to a list of green checks.

One thing that hasn’t been mentioned in the article is l, if you’re doing online validation (on change, on blur, and on focus), if the submit button of the form should be disabled as long as the form isn’t completely valid.
