Masha - AFAIK, this is a Russian girls' name, and I don't like it on a boy at all. It looks as if they wanted
Sasha, but sacrificed it for the stupid M theme.
Micheal - a bit too plain and overly safe, but there's nothing wrong with it IMHO
Marcus - I prefer
Mark, but
Marcus is OK.
Marco would have been nicer since they have Italian roots.
Ashley - nmsaa on a girl
Victoria - fine
