Question

Проверьте, пожалуйста, правильность употребления глаголов. СРОЧНО! – You (see) that man over there? – Which man? The man in the brown jacket? – No, I (talk) about the man who (wear) the blue shirt. – Oh, that man. – You (know) him? – No, I (think, not) so. Are you seeing that man over there? - Which man? The man in the brown jacket? - No, I am talk about the man who wears the blue shirt. - Oh, that man! - Do you know him? No, I am not think so. - I\'m not know him either.

Answer 1

глагол see не имеет форму продолженного времени, поэтому вначале: 
Do you see...
- No, I am talking (в настоящем продолженном к основному глаголу всегда добавляется ing-окончание). 
No, I don't think so. - I don't know him either.

Answer 2

Первое предложение неправильное_Do you see that...?-потому что глагол see не употребляется в Continious
No,I am talking about the man who is wearing...Все действия происходят сейчас,в момент речи, поэтому в обоих случаях Continious
No,I do not think so.
I do not know him either

Answer 3

Are you looking at that man over there? - Which man? The man in the brown jacket? - No, I'm talking about the man who is wearing the blue shirt. - Oh, that man! - Do you know him? - No, I don't think so. - I don't know him either.
