The definition of fin on a rocket would be, a thin, protruding piece of metal whose function is to provide aerodynamic stabilization when the rocket is in flight.
A fin on a rocket acts as a stabilizer during flight by providing aerodynamic stability. It does not fit the traditional definition of a simple machine, as it does not perform mechanical work through movement or force multiplication.
There does not appear to be a "best" size. It depends on a number of factors, to include the bottle used (brand of drink & manufacturer), type of rocket, distance aiming for. One common element to consider is drag. Larger fins have greater surface and mass which will directly affect the altitude your rocket can reach.
The rocket is launched upward into the sky during a rocket launch.
The rocket equation does not directly account for drag in the calculation of a rocket's trajectory. Drag is typically considered separately in the analysis of a rocket's flight path, as it is a complex force influenced by factors such as air density, velocity, and the shape of the rocket. The rocket equation primarily focuses on the relationship between the mass of the rocket, the velocity of the exhaust gases, and the velocity of the rocket to determine its overall performance and capabilities.
An air rocket typically flies faster than a rubber band rocket. Air rockets are powered by compressed air released through a launch pad, providing more force and speed compared to a rubber band-powered rocket.

fin and tip (cone).
A longer fin has increased aerodynamic drag. The geometric relationship between the drag caused by the fins and the center of gravity of the rocket determine the stability of the rocket in flight. Less aerodynamic drag means the rocket can go higher or farther, but it also means the rocket is less stable in flight. This tradeoff has to be considered in the design of the rocket.
It helps stabilise the flight
yes
There the most aerodynamic of fin shapes.
Possibly to produce stability or a semi-controlled flight (?)
A rocket body tube is the center of a rocket; also the piece that holds the rocket together.

A rocket exhaust nozzle that can be aimed in any direction.
