Check an English translation of a Swedish piece for accuracy

I have put this down under translation although it is really a job of proofing. I have a short play (1000 words) in Swedish and translated into English. I want to check that the translation is correct. By that I mean that we haven't misunderstood anything. It is neither about pinpoint correctness nor is it about "a more fluent translation would be". It is just about checking that nothing has been misinterpreted. I am attaching botht the swedish original and the translation. Lines / phrases that give most concern have been highlighted in yellow.

English and Swedish first and second language is what we are looking for here. (Either way round at this stage) not please as third and fourth languages.
