All of the words that end in 's' (except for class) are plural, not collective.

I don't think either gallery or festival are collective nouns. They are simply singular nouns.

Collective nouns are used to refer to a group of people, animals, or things. Here are some collective nouns for the specific categories you mentioned:

1. Festival: A collective noun for a group of festivals does not exist. However, if you are referring to a group of individuals attending a particular festival, you can use "crowd" or "gathering."

2. Family: This is already a collective noun. It refers to a group of people who are related by blood or marriage.

3. Flock: This refers to a group of birds, especially sheep or geese, but can also be used figuratively for a group of people.

4. Crowd: This refers to a large group of people gathered closely together.

5. Parties: In this context, "parties" would not be considered a collective noun. Instead, you could use "group" or "gathering."

6. Army: This refers to a large organized group of soldiers.

7. Village: Although "village" typically refers to a small settlement or community, it can also be used to represent a collective noun for a group of villages.

8. Company: This refers to a group of people who work together in a business organization.

9. Gallery: Generally, "gallery" is not a collective noun. However, if you are referring to a group of art galleries, you can use "collection" or "network" to describe it.

To find more collective nouns, you can refer to dictionaries, thesauruses, or websites specialized in English grammar and vocabulary.
