Technically - they're constantly falling !... They're placed in a high enough orbit so that their forward speed counteracts the (much reduced) effect of gravity.
that is because the 0 gravity keeps it in space and the orbit brings them around without knocking them down or anywhere else
Satellites, by definition, are in orbit. Which means that they're circling their host (planet). IF you were to increase their speed enough, they would. (And if you slowed it enough, then they would fall to the ground.)
weightless
That would totally depend on your mass.
A rocket can rise into the air because the gases it expels with a downward action force exert an equal but opposite reaction force on the rocket. Satellites in orbit around Earth continuously fall toward Earth, but because Earth is curved they travel around it.
They're given enough tangential velocity ('sideways' speed, parallel to the earth's surface) so that the curve of the earth falls away just as fast as the satellite falls.
They are falling but their horizontal motion means that their fall and the curvature of the Earth match so the continually miss the Earth.
Yes, but they do not "feel" gravity, because they are falling - "free fall" in orbit around the Earth.
Because it have some gravity from space.

Kind of, yes. It's a balance between orbital velocity, which is the high speed relative to the ground, and gravity, which is the force keeping the object in orbit.
It usually means that you were in the sky or orbit, and Earth's gravity caused you to fall through the air towards the ground. Basically, falling out of the sky. Which, you most likely would not survive if you hit the ground.

Yes they do.
Satellites orbit the earth for a few years then fall to earth however they are directed to fall to the sea
so you dont touch the lenses and get smears on them and so that the device does not fall and break on the ground
it is easy to fall on a icy day because the ground is very slippy and our shoes dont always have good enouhg grips for the ice.
