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.
Comets and comet composition
Comets are classified based on the length of their orbital period and their origin. Short-period comets have orbital periods less than 200 years, while long-period comets have longer orbital periods. Comets can also be classified based on their composition and physical characteristics, such as size and brightness.
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.
Comets are often referred to as "dirty snowballs" or "icy mudballs" due to their icy composition mixed with dust, rock, and organic compounds.
Comets are made mostly of ice.

Comets and comet composition
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.

it is the time when the tail is facing the north of the other comets like this <halleys tail is north of the other comets when they go > this way
big
I am pretty sure that comets are lighter than moons but it depends on the comet
Because comets cannot decide when they will be visible. It was a natural phenomena and remains so. Comets have a 'year' as do all solar objects. Halleys comets year happened to coincide with the battle. It was a coincidence, nothing more than that.
In the sense that an observer can see tails on comets - no, the gravity and composition of Mars is not favorable to the production of a tail.
