Well I can't tell because you haven't written the question :P
No, the apostrophe in "it's" is incorrect. The correct form is "its" without an apostrophe, as "its" is the possessive form of "it."
Yes if a possession and name of the person are in the same sentence
The correct sentence would be:This is Luke's book.If Luke ended in an s, the apostrophe would be after the s ; since it doesn't, an apostrophe and then an s must be added for possession.Example: Jesus' disciples, John's disciples....
No, the correct way to write it is "associate's degree" with an apostrophe before the "s."

You don't have an apostrophe in your sentence. You don't need one either.

It is correct where you put it.

If you capitalize the first letter of the sentence and place a period at the end, use an apostrophe for the contraction for 'it's', it is a correct sentence: It's going to be a great night today. Although correct as a sentence, it would make more sense if it said: It's going to be a great night tonight.
