They'd, we'd, who'd and you'd.
two contractions for the word won't is will and not.
As far as I know, there is no contractions for the word would. Sorry.
No, it is not.There are contractions for would have (would've) and for would not (wouldn't).
Contractions are formed when two words are combined to create a shorter word. Examples would be "don't" which is a contraction of the words "do" and "not," the word "can't" which is a contraction of the words "can" and "not," and the word "isn't" which is a contraction of the words "is" and "not." Contractions are considered informal language.
Contractions combining a base word and "not" include aren't (are not), isn't (is not), hasn't (has not), and didn't (did not).
Haven't, didn't.

I would say that you could. In theory, all contractions are less formal than the full length version of words, but the word doesn't is used so commonly that it really wouldn't matter to anyone if you used it.
