a comet that passes around earth every 76 years. It has gone by in 1835, 1910, 1986, and will return in 2061
Yes, there are many comets other than Halley's comet. Comets are icy bodies that orbit the Sun and often have elongated orbits that bring them close to the Sun. Some well-known comets include Hale-Bopp, Comet NEOWISE, and Comet Lovejoy.
A cloud of gas surrounding the nucleus.
Nucleus coma tail
Comets are called this because of the ice and dust inside the nucleus. Now go look up everything else on your own.
1 - Halley's 2 - Lovejoy 3 - Hale-Bopp 4 - Ison 5 - Shoemaker-Levy 9 Note: Obviously that's a matter of opinion to some extent. I would have a different list. See "related link" below for a list of some famous comets. Note: Unfortunately, the photo and caption for the "eclipse comet of 1948" is wrong in this link.

Nucleus coma tail
Halleys Comet is by far the best known. The second is harder to determine - Hale-Bopp and Comet McNaught are known at the moment amongst the general public.

You don't need to; the Sun does a fine job of vaporizing the volatile chemicals in the nucleus of a comet.
The solid object at the head of a comet is called the comet nucleus.
