Was the iberian sword really adopted by romans during the camillan period?

As for my guesses

I. I'd go for Equites

IV. I don't know much bout their names. My guesses would be, the first one goes to Equites, second one goes to Hastati and third goes to Rorarii

V. I'd go for Principes for the top left set and bottom right to Triarii

Wild guesses, but that's better than not trying i guess.
