Are these good A levels...?

They certainly complement each other, yes. However, as they are all quite similar in the sense that they require and develop a similar set of skills, they could restrict you in terms of career options. That might not be a problem if you are dead set on going on to a career in English or Sociology (for example, if you want to teach). They are all perfectly good subjects to choose, in my opinion, and good grades in those will build a good basis for going to university or the like. Good luck!
