The first is grammatical, but it is usually followed by something else, such as "every day".
The second is fine.
The third is incorrect. It would be OK with "had" instead of "have".
The fourth is incorrect. It would be OK with "has" instead of "have".
Your last sentence should be "Are they correct?"
