1) I have a question that if I am running a business related to marketing and I am marketing brands which are not halal like alcoholic brands e.t.c.Is that halal?

2) If I am a video editor and I am editing a video in which there is na mahram interaction or any other haram. Is it halal for me if I edit their videos and charge them money?

It is not permissible to work with things that are haram or promote them in any way.
