-------------------------
#1 and #3 indicate the refual(volition) of the subject. Is that right? If we do not stress 'won't,' as in #2 and #4, does each sentence mean a simple future which indicates
'guessing,' 'possibility,' or 'expectation'?

Answer 1

Yes, 1 and 3 indicate firm refusal!

The others simply indicate a future event. Guessing or possibility or expectation are expressed by 'wouldn't' or 'couldn't' or the like.
