So here we've got someone who considers Romanian and Dutch dialects, while elsewhere we have someone who considers Brazilian Portugese and Portugese Portugese two languages.

I doubt you know anyone who knows five languages in your definition (and by knowing, I don't mean travelguide fluency). Such people are rare.

No, but Dutch, English and French are pretty close (hence the reference to Max Weinreich: "A language is a dialect with an army and navy").

They certainly are! I didn't mean to say i know a lot of people that fit the definition - only that I have heard such people mention that it gets easier after the fifth.

I only know Norwegian/Swedish/Danish (close enough to count as one, one and a half), English, Japanese and some French (and marginal German, Spanish, Italian etc due to limited exposure and the intersection of Norwegian/English/French).

I would have to add something a little different, like Sami, Maori, Russian or possibly Farsi, Arabic to fit in the five languages boat.
