Comets are classified according to their orbital periods. Short-period comets, also called periodic comets, have orbits of less than 200 years, while long-period comets have longer orbits but remain gravitationally bound to the Sun, and main-belt comets orbit within the asteroid belt.[5] Single-apparition comets have parabolic or hyperbolic orbits which will cause them to permanently exit the solar system after passing the Sun once.
This seems to be the only classification of comet types. Follow the link below to find out everything there is to know about comets.

Two types.
Type I's tail curves away in a straight line.
Type II's tail curves away in a curve.
I read that on some random website and am not sure I buy it myself, but I didn't find any other reffrence to different types.

There seems to be no evidence that there is more than one type.
They are masses of rock and ice.
