I'm trying to write a paragraph with levels of generality for English. Here's what I have so far... I need help with grammar and punctuation... also does it make sense ?

In the city of Carson, California there is a small house on Mesa Boulevard that is shared among five people, each with diverse interests.
Junior’s room contains surround sound speakers where he listens to music all the time and a book titled “Atheism: The Case Against God” rests on his headboard.
Hector’s room, the biggest of all, has huge Buddhist God statues that are decorated with beads and flowers. In Jose and Carla’s room the King sized bed takes up most of the space; a crucifix hangs on the wall next to a picture of the Virgin Mary.
My room is neither the biggest nor the smallest; it’s perfect. It has decorated lavender drapes, old vintage records hung on the walls, and a King James Version Bible that I read daily can always be found on my bed. We all believe in something. Despite our different styles we are all a family who care and love each other regardless of our religious beliefs.

It has decorated lavender drapes, old vintage records hung on the walls, and a King James Bible that I read daily can always be found near my bed. We all believe in something. Despite our different styles and religions, we are all a family who care for and love each other regardless of our religious beliefs.

Check carefully ... I've made large and small changes.

Your paragraph is well-written and describes the various rooms and interests of the people living in the house. Here are some minor suggestions for improving grammar, punctuation, and clarity:

Junior’s room contains surround sound speakers, where he listens to music all the time, and a book titled "Atheism: The Case Against God" rests on his headboard.
Hector’s room, the biggest of all, has huge Buddhist god statues decorated with beads and flowers. In Jose and Carla’s room, the king-sized bed takes up most of the space, and a crucifix hangs on the wall next to a picture of the Virgin Mary.
My room is neither the biggest nor the smallest; it’s perfect. It has lavishly decorated lavender drapes, old vintage records hung on the walls, and a King James Version Bible that I read daily can always be found on my bed. We all believe in something. Despite our different styles, we are a family who care and love each other, regardless of our religious beliefs.

These suggestions include adding commas in appropriate places, capitalizing proper nouns (like "King James Version Bible"), and rephrasing certain sentences slightly to enhance clarity.

Overall, your paragraph effectively conveys the idea that despite the different religious beliefs and interests of the people living in the house, they remain a loving and caring family. Well done!
