Hmmm, that makes sense.
BTW, the plural of Navi is Nevi'im.
Shophtim, Melumadim, Nevi'im, Saiarim, Sarei Milhama.
And if they were female they would have been:
Nevi'a=>Nevi'ot, Shophetet=>Shophtot, Melumedet=>Melumadot, Sayeret=>Sayarot, Sarat Milhama, Sarot Milhama.
Note: now that I think about it, its better to spell Saiar as Sayar, which is closer in pronounciation to the actual word.
And because I'm suddenly in the mood, I feel like explaining how to actually pronounce the names:
Shophet is pronounced like: shop (without the P) + fat
Melumad is pronounced like: met (without the t) + loom + advertise (without the vertise)
Navi is pronounced like: Narcotic (withouth the rcotic) + Vietnam (without the etnam)
Sayar is pronounced like: Seargent (without the eargent, and imagine an a in there

) + yar (like a pirate, though without the rrrrrrrrrrrrrrrrrrr)
Sar Milhama is pronounced like: Seargent (without the gent and the e

) + Million (without the lion

) + Ha + Master (without the ster)
