"Nu sunt iuți."

Translation: They are not spicy.

[raisage]

Man's not hot ;)

[MortimerCat]

Also translates as "they are not swift". Is threre something subtle making the translation "they are not hot"? Or is it just general context, and in this situation both translations would be correct?

The adjective "iute" can mean either swift (= fast, quick) or hot (= spicy, piquant).
Both meanings are valid in that sentence above, but my first guess was that it refers to some edibles that aren't spicy.

How do you get "they" are not hot as opposed to he or you or we?

[MsGeorgia]

You have to pay attention to the form of the verb and of the adjective:

Eu nu sunt iute - I am not hot/swift
Tu nu ești iute - You are not hot/swift
El/Ea nu e/este iute - He/She/It is not hot/swift
Noi nu suntem iuți - We are not hot/swift
Voi nu sunteți iuți - You all are not hot/swift
Ei/Ele nu sunt iuți - They are not hot/swift
