I'm pretty sure you'll be able to do all of the subjects. In some schools, though, there's a test for Further Maths but sometimes, they require an A* to get into the class but don't worry, I heard that some classes' accept you, if you pass the test.
I'm not sure about other schools, but in my school, you only need a B or over in English Lang. and Maths and 5A*s-Cs to get into Economics but with the revisions in the laws and the fact that some schools have higher expectations, they might require an A or A*. Although, I'm pretty sure that you'll be able to take those A-levels.
P.S.
Sorry for the horrible grammar
