Answer

6 is wrong. Presumably it is a question? In which case one writes
What is there on the table?
9 is wrong. The meaning is unclear. It might mean 9a - My father works from 8 till 7 every day, or, My father works from 8 for 7 hours every day.
11. During the meeting he always speaks - much - a lot.
16. During the lunch we speak about business.
18. Our office is opposite (across from) the/a market.
19. I like to swim in the pool.
20. I live near a/the power plant.
The rest are written in good English.
