Engineers keep the masses of satellites as small as possible to reduce the overall cost of sending them into space, as heavier satellites require more fuel and resources for launches. Additionally, smaller satellites are more maneuverable and flexible in their deployment options in space.
It depends on their purpose - they can be as small as a football - or as large as a bus !
Mars has two known natural satellites: Phobos and Deimos. They're both fairly small. There are also at least two artificial satellites: the ESA's Mars Express and NASA's Mars Reconnaissance Orbiter.
There is more gravitational force between objects with large masses compared to objects with small masses, as gravitational force increases with the mass of the objects. This is described by Newton's law of universal gravitation, which states that the force of gravity is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between them.
A great number of artificial satellites. At any given time, the Earth may have one or more small natural satellites (temporarily captured asteroids) as well.
The number of satellites launched into space in a single day can vary significantly based on the launch schedules of space agencies and private companies. On occasion, multiple satellites can be deployed in one launch, such as when a rocket carries a batch of small satellites. For instance, recent launches have seen over 100 satellites launched in a single day, primarily by companies like SpaceX. However, this is not a daily occurrence, and typical launches tend to deploy fewer satellites.
It is possible, but not likely. Meteors have relatively small masses, without a large gravity well. They tend to lose them because they are in motion.
Objects sent into space need to be made as lightweight as possible due to the huge cost. A large amount of fuel is needed to achieve the required escape velocity and orbital speed for every kg sent - this could be as much 10,000 US dollars per kg (or 22,000 US dollars per pound).

No, it's to small.
Satellite. Satellites can be natural, like the Moon, or artificial like GPS satellites.

It can be natural satellites (moons), man-made satellites or small pieces of matter such as ice (rings of the outer planets).
Phobos and Diemos. Both are very small, as planetary satellites go, and both are suspected of being captured asteroids.
