i'd think that
sakura--kairi (attitude i think~), yuffie seems to make the bill to me too~

syaoran--the white rabbit (

for some reason...i can imagine him panicking after sakura everytime....ahahah~~)
kurogane--cid (bah~they seem alike to me~~

)
fye--chesire cat (how to spell this...its in alice in wonderland, that purple striped cat that vanishes and leaves a grin~

)
mokona--chip & dale, either 1 (well...they seem alike to me~~eheheh~~~)
KHII might be released late this yr....though i'm not sure for the north america version *better mop up my jap language skills~*
