What are the gender of noun give at least 5 examples for each kind?

It seems you're asking about the grammatical gender of nouns, which is a concept found in many languages but not in English. English doesn't have grammatical gender, meaning nouns aren't inherently masculine, feminine, or neuter.

Here are examples of grammatical gender in other languages, like Spanish and German:

Spanish:

* Masculine:

* el libro (the book)

* el sol (the sun)

* el perro (the dog)

* el río (the river)

* el árbol (the tree)

* Feminine:

* la casa (the house)

* la luna (the moon)

* la gata (the cat)

* la flor (the flower)

* la montaña (the mountain)

German:

* Masculine:

* der Mann (the man)

* der Tag (the day)

* der Stuhl (the chair)

* der Baum (the tree)

* der Fluss (the river)

* Feminine:

* die Frau (the woman)

* die Nacht (the night)

* die Tür (the door)

* die Blume (the flower)

* die Sonne (the sun)

* Neuter:

* das Kind (the child)

* das Buch (the book)

* das Haus (the house)

* das Auto (the car)

* das Wasser (the water)

Important Note: English does have biological sex, which refers to the biological distinction between male and female. However, this is not the same as grammatical gender.
