かなりN4
かなり and だいぶ both mean 'considerably', but かなり sounds more objective/formal while だいぶ often conveys the speaker's subjective sense of noticeable change or surprise.
ずいぶんN4
ずいぶん is stronger and more emphatic than だいぶ, implying 'to a surprising extent' rather than just 'considerably'.
よほどN2
大分 conveys 'considerably' in a plain, measured way, lacking the surprised or judgmental nuance often found in 余程.

大たい部ぶN1
大部 read as だいぶ is a rare adverbial usage meaning 'considerably', easily confused with the far more common adverb だいぶ, which is almost always written in kana.
大たい半はんN3
大分 (だいぶ) is an adverb meaning 'quite a lot/considerably' and shares the kanji 大 with 大半, but it does not mean 'majority' the way 大半 does.
