Is it natural to ask "How much money did you spend on this spring festival?" if I want to know how much money my friends spend spent on things like gifts, foods, clothes, etc?

Note my changes above. If you're talking about one specific spring festival that's already happened, as indicated by "did you spend", you need to use "spent" in your main question. If you want to know how much they generally spend every spring festival, your direct question would be "How much do you [usually] spend on spring festival?" (and your longer question would contain "spend" as you originally wrote).
The main wording of your question is fine. You just need to make sure you use the right tense.

I don't think "on" is a good preposition here; people usually say "spend money on something" and here, spring festival is not "something".

So, how about my two new attempts? Are they natural?

a) How much did you spend for the Spring Festival this year?
b) How much money did you spend on this Spring Festival?

I don't think "on" is a good preposition here; people usually say "spend money on something" and here, spring festival is not "something".

I disagree. In BrE, at least, we might ask someone "How much did you spend on Christmas last year?" We're asking about their total spend for everything involved in the Christmas season - presents, cards, food, booze etc.

So, how about my two new attempts? Are they natural?

a) How much did you spend for the Spring Festival this year?
b) How much money did you spend on this Spring Festival?

I don't find a) natural for the reasons given above. I'd say b) is OK. I notice that in post #1 you wrote "spring festival", but you've now capitalised it. Is it the official name of the festival?

You don't need the word money in any of your sentences.

I don't like the preposition 'on' because, as you say, you don't buy Spring Festival.

In my opinion, if you're thinking of Spring Festival as an extended period taking place over several days (which I think you are), then 'over' is the best choice, and if you're thinking of Spring Festival as an upcoming event to prepare for (which you may be), then 'for' is the best choice.

How much did you spend over this Spring Festival?
How much did you spend for this Spring Festival?

With the first meaning, it's even simpler to refrain from using any preposition at all:

How much did you spend this Spring Festival?

I don't like the preposition 'on' because, as you say, you don't buy Spring Festival.

Out of curiosity, then, would you not say "How much did you spend on Christmas?"

With 'on' it means that you see Christmas as one single commodity to be paid for. Now I'm sure that will make perfect sense sometimes, yes, and I didn't mean to say it was wrong to view Christmas like that, but just that I don't like it, and especially not in this particular context. I was really guessing at what Silverobama might mean, in order to select the best preposition for the job. I don't know how Spring Festival spending compares with Christmas spending, or how Spring Festival is viewed by Chinese people, but it may be that 'on' is indeed the right choice, and that the OP is indeed thinking of Spring Festival in this way.

 

[Silverobama]

Is it the official name of the festival?

Yes. But now it's called the Chinese New Year more often. Spring Festival has become less and less common.

Note my changes above. As a learner, don't try to start sentences with "but". Use it as a conjunction. Don't use an article before the name of a festival/holiday. In English, it's just "Chinese New Year". I didn't realise it was the same thing as Spring Festival.
