Answer 1

Mostly, the order of the vendor prefixes aren't that important, but be sure that you are using the most standarized version by add the one without the vendor prefix (just flex) at the end. The CSS always prioritize the last if the properties are equal.

Anyway, the flex without prefixing is now supported by the most common browsers: http://caniuse.com/#feat=flexbox. 96% of the browsers can use flexbox, and 82% of them do support flex without prefixing.
