I knew someone who took French, Spanish, Latin and Greek for A level, so it's definitely possible to do 2. If you enjoy them, go for it!
DON'T DO IT!
I was in a similar situation to you, I excelled in two languages at GCSE (French and German) and then decided to do them for A Level but it's been such a bad decision! I am struggling a lot with both of them. I used to find them so easy but one language is hard enough on its own at A Level, without the added complication of another one! I used to ignore people when they said it wasn't going to be easy at all, but I wished that I had listened to them! It's not as if I'm a bad student, I mean, I'm predicted four As for AS but I don't think i'm gonna get anywhere near as good as that now because of how bad the languages have been!
