Does "all alone" have stronger nuance than just "alone"? What's the difference between those two?

Yes, "all alone" expresses the same meaning as just saying "alone", however the "all" adds emphasis on the person being alone and it gives it a bit of a stronger meaning. "All alone" is sometimes used with a bit more of a negative or sad nuance while "alone" is usually more neutral. Ex: I am alone in the house. Ex: She is all alone on her birthday this year.
