Hello,
English Literature and Religious Studies seem fine for Law. Although, the top universities (and most of the Russell Group) may see Philosophy and particularly Politics as slightly weaker subjects. Trinity College, Cambridge lists Politics as one of its less preferred A-level choices.
Other suggestions (apart from History) could be Mathematics, Biology, Chemistry, Physics, Economics, Sociology or a language subject.
The universities your looking at (Russell Group and top of the league table) will require A*AA/AAA grades for entry to Law as it's highly competitive. For Theology/Religious Studies the entry requirements will be anything between AAA - ABB.
Also, fifth option?? Why do you have to take five? Universities usually only ask for 3 A-Levels and 1 AS. Does your sixth form/college require you to take five?
