Generally, periods (to signify the end of sentences) will always come after apostrophes. Quotation marks and parentheses will go outside of the period, but apostrophes go inside.
In American English, a period goes inside the closing apostrophe when it ends a sentence. However, in British English, the period goes outside the closing apostrophe. For example, "I love eating Pizza." (American English) or "I love eating pizza". (British English).

In American English, periods are typically placed inside quotation marks at the end of a sentence. However, in British English, the period is placed outside the quotation marks unless it is part of the quoted material.
The apostrophe in "rhinoceros" to show possession should go after the "s", making it "rhinoceros'".
In American English, commas and periods typically go inside quotation marks. Question marks and exclamation points go inside if they are part of the quoted material and outside if they are not. However, in British English, the punctuation goes outside the quotation marks unless it is part of the quoted material.
The word "states" does not require an apostrophe for pluralization. It remains as "states" in its plural form.
No apostrophe needed in the sentence "The turkey has two ears."
Outside, like: The car was John's, so he had to pay for the repairs. However, if you are using the apostrophes as single quotation marks, then inside. Commas and periods always go inside quotation marks. "Like this."
Outside. (But if the entire sentence is a parenthetical like this one, it would go inside.)
No before it.
Periods should typically go on the outside of parentheses. However, if the entire sentence is contained within the parentheses, then the period should go inside.
In American English, the period always goes inside the closing quotation mark, regardless of whether it is part of the quoted text or not. In British English, the period can go inside or outside the quotation marks depending on the context.
A period would go inside parentheses to finish a complete sentence, but you always need sentence-ending punctuation outside of the parentheses.
The period always goes inside quotation marks - in all kinds of sentences - not just ones that have a song title.
