My short answer: This lot, plus From Russia with Love.

My slightly longer answer: From Russia with Love is my all-time favourite Bond film, followed by Goldfinger (as you may be aware, and as I've written about elswhere). However, there is a difference between "favourite" and "greatest", as you make clear in this article. Furthermore, there's also a difference between "classic" and "great" or "masterpiece". I'd argue certain films become classics over time due to iconic popularity, without necessarily taking on the status of being "great" or a "masterpiece". I think calling any Bond film a masterpiece in that sense is probably a tad over-generous, but they are certainly hugely influential and the "great" ones are those you've listed (except From Russia with Love, which definitely belongs on that list). :)
