Yes, English horns are played in orchestras. There are about 3 to 4 of them, and they sit next to the oboes in an orchestra setting.
Yes, it is. Lots of classical music is played by a symphony orchestra. There are thousands upon thousands of classical orchestral works - too many to list here.
A symphony is like an orchestra but a symphony is an extended musical composition in Western classical music, scored almost always for orchestra. Symphonies have flutes, clarinets, basses, celloes, first violins, second violins, violas, harp, piano, bassoons, oboes, horns, trumpets, timpani, percussion, trumbone and tuba.
Yes and no. The classical composers standardised many of the elements of the modern orchestra, such as having a general string section, and two parts for flutes, oboes, clarinets, bassoons, horns and trumpets. Beethoven introduced the trombone as an instrument for non-sacred works for the first time. However, the Romantic composers then added both different instruments (often percussion, or country-specific), and usually had larger orchestras (more string players, four or more horns, etc.) The basic formation was established in the Classical period though.
