This is a question about notation. If you were given such a question, you clearly are expected to know what things such as " $0\le x\le 1$" and " $\x\in \{0, 1\}$" mean. Do you not know that? The notations should be given in your book.

The fact that "x is a natural number" is crucial here. Once you have found out what the various notations mean, write down the values of all natural numbers that satisfy each.
