Yes. Every thing that has mass (on Earth, we call it 'Weight') attracts every other thing with mass. It is correct to say that any two things with mass attract each other. For instance, the Earth pulls on you because of the force of gravity, but you pull on the Earth right back - only by a tiny amount, but still . . .
The Earth and Sol, the Sun, attract each other, and both attract the Moon. The same way, Earth and, say, Mars or Venus attract each other, but only by a relatively small amount due to the large distances between them.

Mass is not weight! Whatever the Space Station's mass if it could be landed, it has the same mass in space, but there it is weightless, or practicably so.
The Sun AND its planets attract each other with gravitic force.
The other planets do have gravity.
The Earth is not a magnet that may attract a body to the ground. The force of gravity of the Earth is balanced by the force of gravity of the other planets and the Sun. So you can walk. ( Einstein's famous equation.)
No. Earth's magnetic field only affects earth, not other planets.
Since no one from Earth has visited another planet, and we have no indication that there is anyone on the other planets, Earth does not help other planets in any way. Why do you think there is something Earth does to help them- whoever them is.
yes, the earth and other planets revolve around the sun
Earth and the other planets are mostly made of rock.
Earth and the other planets are mostly made of rock.
The other planets actually do have seasons.
Studying the earth helps scientists to understand other planets since the earth is part of the solar system. Scientists use the features of the earth to compare them with what other planets hold.
Astronomers have found Earth-sized planets in other solar systems.
