I don't force jobs in these games, but some of the characters share some characteristics from jobs from he earlier games, but I can't put jobs on some of them. This is what I've thought of so far. Some are given, obviously. I'll write them anyways.

VII:
Cloud = Fighter. He carries a sword and the main protagonist is typically a fighter.
Cid = Dragoon. He has Jump.
Aerith = White Mage.
Tifa = Monk
Yuffie = Thief/ninja
Red XIII = ???
Vincent = ???
Barret = ???
Cait Sith = ???

VIII:
Squall = Fighter. Same reason as Cloud
Zell = Monk.
Quistis = Blue Mage
Rinoa = ???
Irvine = ???
Selphie = ???

X:
Tidus = Fighter.
Auron = Samurai
Lulu = Black Mage
Yuna = White Mage/Summoner
Rikku = Thief
Kimarhi = Dragoon/Blue Mage
Wakka = Monk?
