Yes you can see the satellites in space at night even with the naked eye.
You won't see the entire satellite with the naked eye but you'll see glimpses of the satellites during the night if you look up into the sky.
The satellites will look kind of like stars in the sky.
Basically when you're looking at the sky to see a satellite the satellites you're looking for will look like a star that is steadily moving across the sky for a few minutes.
Satellites are more easily viewed away from city lights and in cloud free skies.
You can see a light kind of twinkling or flickering in the sky and that usually is a satellite.
To see more of a satellite you'll need a good telescope.
