Out of the provided sentences, I'll correct them for you:

1. Mr. Steel has been working here for years. (This implies that he started working here years ago and is still working here.)
2. They've been studying hard lately. (This suggests an ongoing action of studying.)
3. You look hot! Have you been cooking? (The present perfect continuous "have been cooking" is appropriate here since it implies a recent activity that might have caused the person to look hot.)
4. I have known her for a long time. (The present perfect "have known" is correct here to indicate that you have been acquainted with her for a long time.)
5. What have you been doing since lunchtime? (The present perfect continuous "have been doing" is suitable here to inquire about activities that have been happening since lunchtime up to the present moment.)
