If someone uses two question marks at the end of a sentence what does it mean? For example "can I come over?" ?

Well is it urgency etc things like that

Only a single question mark is used at the end of a sentence or quote.

When writing dialog, it is possible to use two question marks in a sentence, with the first question mark replacing a comma.

Follow on: Using two or more question marks (or two or three exclamation points) might be acceptable in informal writing, but it has no basis for it in formal writing, where it would be considered a punctuation error.

As @logan_v96 already stated, a second question mark is meaningless.

[Logan_V96]
