"I'll not", "I'd not", and "I've not".

[Space60]

Do you ever use "I'll not", "I'd not", or "I've not"? I don't. I would use "I won't", "I wouldn't", and "I haven't". Pronoun contractions are only natural with forms of "be not" for me.

"I'm not"
"You're not"
"He's not"
"She's not"
"It's not"
"They're not".

I generally don't contract will not, have not, or had not with the subject — I strongly prefer won't, haven't, and hadn't — even though I readily contract is (and related forms), was, will, would, have, had, and so on with the subject - even if the subject is not a pronoun — provided the verb is not negated (except in the case of is and related forms, where I am in free variation except in the case of negated am, where subject contraction is strongly preferred).

[Richard W]

Yes, though I'm not sure what determines my choice. I think I have a subtle difference between I've not seen that before and I haven't seen that before. The former suggests that not seeing is not due to inattention.

Yes, same here. This is because my variety doesn't have "amn't" or "ain't", and "aren't" is only permitted in the tag question "aren't I?

[Man in Space]

I use these forms in conversation on occasion. Not sure 100% what the deciding factor is.

Exactly the same with me too.

I use the first and the third regularly. The second occurs most often as "I'd rather not."

I do strongly favor I'd rather not over the alternative even though I generally do not use I'd not by itself much.

[Jonlang]

No, but I feel like these are more common in areas like Lancashire and Yorkshire.

[sangi39]

I've used all three, especially "I've not", and tend to a bit more often when talking with other people from round here (North Yorkshire). It does seem to be faitly common up here than, say, down south, but does seem to be less common among younger speakers than older ones, so I feel like Jonlang's on to something on that front

[vegfarandi]

I don't think I ever say the first two but the last one seems plausible in for example "I've not done that before" and "I've not really tried that."

I feel the same way about these myself.

Wiktionary has entries for "I'dn't" (I would not), "I'ven't" (I have not), and "I'mn't" (I am not). It lists them with a nonstandard label.

I'd struggle to hear a difference between "I'ven't" and simply "I 'aven't" because the clipped "have" usually begins with a schwa here.

I don't have these. However, I readily drop the initial /h/ in have/had and haven't/hadn't.

[Travis B.]

Does anyone else have a clitic initial /j/ for you? For instance, I can pronounce you have as /jæ(v)/, you haven't as /ˈjævən(t)/, and you don't as /joʊn(t)/.

I don't have those contractions, but when speaking quickly, you have can sound like /jhæv/, and you don't can sound like /jdount/.

My favorite is when I stack clitics so as to have /djæv/ for do you have (note that in this case I never coalesce /dj/ to *[dʒ]).
