Chopin was born in 1810. He was a Polish composer. He was a prolific composer for the piano.
None, unless the composer has included it in the piece being performed. The composer of classical works specifies which and how many of each type of instrument are used for his/her piece. When the piano is called out in the score, usually one piano is used.
A LOT of people. Beethoven, Mozart, Haydn, McDowell, Liszt, Rachmaninoff, Schubert, Schumann, Faber & Faber, etc...even my teacher, and me myself. As long as someone made a composition of some sort, that person is a composer, and if he/she composes a piece of music for the piano, that person is a composer for the piano. Which means that if you play the piano and create a 10-measure piece, you are still a composer. Perhaps not wide-known, but still a composer.
