Please help identify these questions (there are 5), thanks a bunch!

No.3 is EXTREMELY popular and sounds familiar, but I just forgot what exactly it is.

[Opus106]

It's trademark Tchaikovsky. I think it could either be from one of his symphonies or Romeo and Juliet.

OK, No.3 is done, it's been confirmed (Romeo and Juliet). Does anyone know the Chopin like piece (No.2)?

Is this for class or something?

1. Schubert - I think Erlkonig is the name or something like that.
2. It does sound like a Chopin mazurka, but I haven't heard them all, so I don't know
3. Wow, not a tough one by any means! 
4. I believe it's the Brahms violin concerto
5. No idea

[Novi]

2. Schumann, 'Aufschwung,' Fantasiestücke op.12
Oops, right composer, wrong piece . 'Florestan,' Carnival op. 9
(should check before posting )

5. Brahms, Intermezzo in E flat minor, op. 118/6
