the sound comes from the vibration of the air as it passes the reed. the pitch of the sound is changed by changing the length of the column (thus forcing the wavelength to become longer) by holding down more keys.
The flute can produce multiple octaves by changing the way air is blown into the instrument and by using different fingerings to change the length of the vibrating air column. This allows the player to produce higher or lower pitches across different octaves.
Resonance in a horn is produced when the vibration of the player's lips on the mouthpiece matches the natural frequency of the air in the instrument. This causes the air column inside the horn to vibrate as well, amplifying the sound. This phenomenon is what allows the horn to produce a clear and powerful tone.
A flute produces sound when a player blows air across a hole in the instrument, creating vibrations in the air column inside the flute. These vibrations travel through the flute and are amplified by the instrument's shape and material, producing the sound that we hear.

None. The column of air inside the instrument vibrates. Compare this to a string instrument -- the string vibrates, of course. With the reed instrument, such as a clarinet or bassoon -- the reed vibrates. The vibrating reed causes the column of air inside the instrument to vibrate. However, the brass instruments do not have vibrating parts. What makes the column of air vibrate is the buzzing of the player's lips!
Instruments that produce sound by a vibrating column of air include woodwinds and brass instruments. Examples of woodwinds are flutes, clarinets, and saxophones, where sound is generated by air vibrating within a tube. Brass instruments, such as trumpets and trombones, create sound through the vibration of the player's lips in a mouthpiece, causing air to vibrate within the instrument's tubing. Both categories rely on the resonance of the air column to amplify the sound produced.

No, the clarinet is a woodwind instrument. A clarinet uses a reed to produce sound instead of using a mouthpiece and the player's embouchure to produce sound like brass instruments do.
No, they are two different families of musical instruments. Brass instrument produce sound by the vibration of air though a mouthpiece created by the vibration of the player's lips. A percussion instrument produces sound by being struck, scraped, or rubbed by the player's hand or against another instrument to create sound.
The finger holes on the side of a piccolo allow the player to change the length of the column of air inside the instrument, which in turn alters the pitch of the sound produced. By covering or uncovering these holes with their fingers, the player can effectively change the frequency of the vibrations and produce different notes.
