Yes, but it's quite uncommon. The contracted form of "Will have" is "will've". This only works for things you'll do in the future, e.g. "By Wednesday, I will've completed that assignment" and does not work for things that you'll acquire (e.g. "For Christmas, I will've a new pair of jeans".)
'can't'
"Where'd" can be a contraction of either "where did" or "where would": Now, where'd I put it? I just had it five minutes ago. Where'd you like to go for dinner?
after the t (it's) You put an apostrophe on 'its' if it's a contraction of "it is." Otherwise, 'its' has no apostrophe because that's its nature.
You'll use an apostrophe s on the word son if you are showing possession or using a contraction. Examples: "That is my son's room." "My son's out at the moment" -- This is a contraction of "son" and "is"
There is no contraction. The contraction we're means "we are."
I'd
It's is the contraction for it is....so if you are using the contraction, use the apostrophe. If you are not, then do NOT use it.
'can't'
The correct form is "I'd" which is a contraction for "I had."
i don't because i put it on there
Shouldn't is the correct contraction for should not.
The contraction or "you would" is you'd. It is also the contraction for the phrase "you had." In either case, the apostrophe goes where the letters were removed.
"Where'd" can be a contraction of either "where did" or "where would": Now, where'd I put it? I just had it five minutes ago. Where'd you like to go for dinner?
The contraction for "will not" is "won't."
after the t (it's) You put an apostrophe on 'its' if it's a contraction of "it is." Otherwise, 'its' has no apostrophe because that's its nature.
No, you do not need to put an apostrophe in the word "hundreds" unless you are indicating a contraction or possession.
The contraction for I would is I'd. I'd go see a doctor if I were you.
