Explanation:

A nonrestrictive modifier adds extra, non-essential information to a sentence and is set off by commas. The information can be removed without changing the core meaning of the sentence.

1. "My brother, John, is my favorite of all my brothers.": "John" is nonrestrictive here (the sentence still makes sense without naming him, as it specifies he's a favorite brother) and is correctly set off by commas.
2. "My oldest sister, Maria, is a pilot.": "Maria" is nonrestrictive (the sentence works if we just say "My oldest sister is a pilot") and is properly punctuated with commas.
3. "My two best friends, Tory and Monica, met me at the movies.": "Tory and Monica" is extra information (the core sentence is "My two best friends met me at the movies") and is correctly set off by commas.
4. "The book, Robinson Crusoe, is a classic.": "Robinson Crusoe" is nonrestrictive (the sentence is clear without the title: "The book is a classic") and has correct comma placement.
5. "Bulldogs, which I love, are the cutest!": The clause "which I love" is nonessential extra information and is properly set off by commas.
