Answer 1

1. I have more than five books.
1-2. I have over five books.
(Does it include five books?) <b>Yes, these are fine and your interpretation is right.</b>

2. I have five or more books.
(It includes five. At least I have five books. Am I right?) <b>Yes</b>

3. I have <b>fewer </b>than five books.
4. I have under five books.
( I don't have five books. I have at most four books. Is my explanation right?) <b>3 is now correct; "books" is a count noun, and needs "fewer" instead of "more" (used for non-count nouns). Let me know if you need more explanation about this.And yes, your explanation is correct.</b>

5. I have five and more books.
(Can we use this expression? At least I have seven books. Is it right?) <b>These are a bit off. I'd say, "I have at least five books" or "I have at least seven books."</b>

1. I have more than five books.
1-2. I have over five books.
(Does it include five books?) Yes, these are fine and your interpretation is right.
--------------------
Doesn't it mean that I have six or more books?

"More than five books" doesn't include 'five books.' Is that right?

Answer 3

"more than five books" means that you have at least six! It includes the five and adds at least one more.
