Yes, those are correct categorizations of nouns.

Proper nouns are specific names of people, places, organizations, or things. In this case, "Sam," "Burger King," "she," and "the girl" are all examples of proper nouns. To determine if a noun is a proper noun, you can check if it refers to a specific entity that is capitalized.

Regular nouns, on the other hand, are general names for people, places, things, or ideas. "Microphone," "table," "spoon," and "milk" are regular nouns. These nouns do not refer to any specific entity and do not require capitalization.

By understanding the distinction between proper nouns and regular nouns, you can correctly identify and categorize different types of nouns.
