Answer

Su.Ki is correct.

Answer

If you are talking about the period from now until 2026, the expression you need is 'the next ten years'.

'I'll keep you company for the next ten years.'

If you say 'I'll keep you company in ten years from now', it has a different meaning. It means that you will start keeping the person company in 2026.

Answer

You should use "in".

Answer

Sentence 2 is correct if you say what will happen in 10 years:
In 10 years from now, I will ...
But it would sound better if you didn't add the "in" :
10 years from now, I will..

However this means that not until ten years have passed will you keep this person company.

I think the word you're looking for is a "decade" - this means 10 years.
I will keep you company for a decade.
I will keep you company for 10 years.
