(Does #1 mean #2, 3, 4, or 5?)
#1 could mean the same as any of the others, depending on the intention of the speaker. I see 1 and 2 as close to each other in meaning, and 3, 4, and 5 as close to each other in meaning.
The primary difference is in the meaning of the auxiliary verbs "would" and "must."
