It depends on the context you are writing the phrase in. Generally the phrase "I wonder" is followed either by a question mark or ellipses (...). If you say, "How many stars are there in the sky, I wonder?" you would use the question mark. If you are saying something along the lines of, "Hmm, I wonder..." as if to indicate that you are formulating an idea or a plan in your mind, ellipses are appropriate.

No, a period does not come after a question mark in a sentence. The use of a question mark indicates the end of an interrogative sentence, while a period is used to end a declarative sentence.
No. it's not necessary to put a period after a question mark.
No, a question mark alone is sufficient.
No, a period is not used after the reference when an in-text citation ends with a question mark. The question mark serves as the punctuation at the end of the sentence, and adding a period would be redundant.
no you can't because a period is already a punctuation but you can add an exclamation mark after a question mark to make a surprised sound but that's unformal
In casual writing you might be able to replace a question mark with a period, especially in dialog to indicate intonation, but usually the sentence structure of questions is different, so that a period will not be correct. For example, "Where did you go?" is correct as a question, but "Where did you go." is not correct.
No. A question always has to end with a question mark.

A sentence which begins with "I wonder..... " is usually ended with a question mark, as it is normally a way of phrasing a question.I wonder if it will rain tomorrow?
While pressing the left shift key (to the left of [z]), press the [ / ] key ( to the right of [ . ]). This question does make me wonder how you put a question mark at the end of it though.
The two common sentence signals for the end of a sentence are a period (.) and a question mark (?). A period is used for declarative and imperative sentences, while a question mark is used for interrogative sentences.
