1. (I) Adverbs of degree very, quite and a bit
An adverb of degree makes the meaning stronger (+) or weaker (-):
(++) very cold (+) quite cold) (-) a bit cold
An adverb of degree (e.g.) goes before an adjective or an adverb: e.g. fairly soon, a bit tired
We can use a lot (++) and much (++) with a comparative: a lot cheaper, much faster

2. (II) Adverbs of degree
Many adverbs of degree (e.g. really) can go with a verb. Most go in mid position (after an auxiliary but before the main verb: My foot is really hurting (++), I just know you’re wrong (++)
These adverbs go at the end of a sentence when they describe a verb: much, a lot (++); a little, a bit (-); terribly, awfully (++):
I ride my bike a lot or let’s rest a little
In a positive stament we use very much, in a negative very much or much: I like this book very much. NOT I like this book much

3. (III) Adverbs of degree: quite and rather
Quite usually means “fairly”: I feel quite tired now
When we make a favourable comment, we usually prefer “quite” to “rather” : It’s quite warm now, isnt’t it?
Rather in a favourable comment means to a “surprising or unsual degree”: It’s rather warm for October
In unfavourable comments we use rather, but quite it’s possible: The floor was rather/quite dirty.
We can use rather with a comparative, but not quite: The second test was rather easier than the first
Quite can also means completely: the idea is quite absurd
