Can we use all the expressions? Do they have the same meaning? Which ones are commonly used?

All are fine and mean the same thing, yes. There's a typo in 6, though, that needs correcting.

Yes, all of the expressions you provided can be used to convey the same meaning, which is asking someone to wait for a short amount of time until the speaker is ready.

However, there are slight differences in usage and commonality.

1. "Give me a minute" and "wait a minute" are the most commonly used expressions. They are straightforward and commonly understood, making them the go-to choice in most situations.

2. "Give me a moment" and "wait a moment" are similar in meaning to the first group, but they imply a slightly shorter duration of time. They are less commonly used but can still be understood by most people.

3. "Give me a second" and "wait a second" indicate an even shorter amount of time, suggesting that the speaker will be ready very soon. These expressions are less commonly used but are appropriate in situations where urgency or impatience is emphasized.

4. "Just a minute," "just a moment," and "just a second" are similar to the previous groups but contain the word "just," which indicates that the wait will be brief. These expressions are also commonly used and can be used interchangeably with the first group.

Overall, "give me a minute" and "wait a minute" are the most commonly used expressions, while the others may be used in specific contexts or to convey a sense of urgency.
