Neither. Use "He has been working for the last five years."
Present perfect continuous eg has been working is used with for and since as time markers
For is used with a period of time eg for ten years, for 10 minutes, for the last five years.
Since is used with a point in time eg since wednesday, since 10 am, since last year, since the holidays
No. "I have known him for 5 years." Would be more correct.
Only the second sentence is correct: (John has been working here since August). Hope that helps. The first example could be correct if you susituted "is" for "was." Example: John was working here since August...although it would need to have something followed such as "John was working here since August, but he has since left the company.
The correct grammar is "You have been here for four months."
No, the sentence is not grammatically correct. It should be: "It had been a long time since I had written to you."
Yes, that statement is correct as a way to indicate the passage of one month since the letter was posted.
No. "I have known him for 5 years." Would be more correct.

No. She is working. She has been working.
No. The proper phrasing would be:"I haven't been with my daughter for four years (now)." (now is understood)The word since is used to date from a specific past event or time, e.g."I haven't been with my daughter since my divorce four years ago.""I haven't been with my daughter since 2008."It can also be phrased colloquially using since to introduce a clause:"It has been four years since I was with my daughter."(meaning it has been four years since the last time I was with my daughter)
Tim Burton and him have been working together for 25 years since 2010
Sentence is understandable but not correct. A correct version that can possibly be used would look like "I've been busy with the Dutch language since two years ago". The reason the original sentence doesn't work is because 'am' is describing the present tense but 'since' describes the past, so there is conflict.
