Are my A-level choices good?

I am aiming for top unis and russel groups and I want to study physics or astrophysics. I am doing A-levels: Maths,physics,geography and German.
I was wondering if this would let me study physic in those unis?

You can easily find this out yourself by going on the university websites of your choice and searching the course of Physics. Then look at entry requirements. If they accept those a levels then your fine.
Its your choice what schools you want to apply for and there are loads od Russel group uni's so you have to do your own research on what's good for you, the location, the modules, and entry requirements. Just spend a day doing the research but it's okay if you cant make an immediate decision on the 5 uni applications. You have time.
