I recently saw the International Space Station without a telescope. Are there any other man-made space objects that can be seen using bare eyes?

Yes, there are quite a lot of them, but ISS is by far the brightest. The other satellites can be visible with magnitude fainter than 3. "Can be" means in dusk/dawn, when the satellite is in the sunlight.
