Without the sentences provided, I can't determine which sentence uses commas correctly.
No, commas are not necessary between each "ha" in "hahaha." The word "hahaha" is typically written without commas or other punctuation marks.
Without seeing the examples you provided, I can't confirm which one uses commas correctly. However, in general, commas are used to separate items in a list, set off introductory phrases or clauses, and separate independent clauses in compound sentences. Make sure to check for consistency and clarity when using commas.
It depends on the context. There is no word that always requires commas before or after it. Here are some examples using "though" with and without commas:Though not required, reservations are suggested.He was impulsively generous, though he did not have much money.I could see, though, that something was not right.
"Which" is used to provide additional, nonessential information in a sentence, set apart by commas. "That" is used to provide essential information, without commas, and is critical to the sentence's meaning.

Easy, the commas separate the numerical units. 1,000 is one thousand. 1,000,000 is one million and so on.
1,045,620
If you put the commas in, you'll see that the number is 12,000. This is twelve thousand in spelling.
140.000.000.000.000 (use commas in UK).
6000000
40005003 or 40,005,003 (with commas for readability)
That sentence is best without any commas at all.
In between the 20 and the three zeroes. So it should look like this: 20,000.
