Looked through your other typings now, too
:
Mary - we see relatively little of her, but I'd sooner try Ij, for sheer persistence she shows. Ip is unlikely, though Te-creative is still more possible than for example Fe-ego.
Kitty & Lydia - apart from them being giggly teenagers, I don't think there's much to say. Fe or Fi creatives is as far as I'd guess.
Mr. and Mrs. Gardiner - too little info again, but they rather seem Fi/Te. LIE and ESI could work.
William Collins - ugh... no idea, he's too much of a caricature. About any type is possible, probably.
Charlotte - Te-dominant, not sure which one.
Mr. Charles Bingley - Fi-creative sounds about right. He seems IEE over SEE, and it makes far more sense with Jane as Delta NF.
Caroline - I rather think she might be IEI over EIE, but both work and neither strucks me as obvious.
Georgiana - we see nothing but shy and hurt girl who doesn't have her own opinion. I really think it's impossible to say anything but that she's likely to be an introvert.
Wickham - SLE or SEE, both work.
