Yes
Assuming that the only force on the two objects is an electric force. Felectric = k Q q / r2 This is Coulomb's law. K = electrostatic constant, Q and q are the magnitudes of the point charges, and r is the distance between the point charges. As you can see, if you decrease the magnitude of the charge, the electric force decreases. In other words, the objects are less attracted to one another. aside: gravity happens to be modeled the same way.
According to the law of conservation of electric charge, total electric charge in an isolated system remains constant. Electric charge cannot be created nor destroyed; it can only be transferred from one object to another.
The fundamental difference between the forces of gravity and electromagnetism is that gravity is a universal force that acts on all objects with mass, while electromagnetism is a force that only acts on objects with electric charge. Gravity is a long-range force that attracts objects towards each other, while electromagnetism can attract or repel objects depending on their electric charge.
No, a moving electric charge surrounded only by an electric field would not be considered an electromagnetic wave. Electromagnetic waves are a combination of electric and magnetic fields oscillating perpendicular to each other and to the direction of propagation. A moving electric charge in an electric field alone would not exhibit this characteristic.
No, it only takes a single charge to create an electric field. The strength of the electric field depends on the magnitude of the charge and the distance from the charge. Multiple charges can interact to create more complex electric fields.
Neutrons have no electric charge so there isn't an electric force. Only with electrons and protons.
Not enough information. You not only need to know the distance, but also the electric charge - not just that it is "positive", but the exact amount of charge.
Atoms have NO electric charge, only ions have (+ or -)
Yes. Gravitational force is proportional to the mass of the two objects and inversely proportional to the square of the distance between them. Charge does not enter into the picture.
Since neutrons have no charge, they are not influenced measurably by an electric field.

In case of electric force there are both repulsive and attractive. But in case of gravitational force, only attractive force. Electrical force between electric charges. Gravitational force between masses. In electric force we use a constant known as permittivity of the medium. But in gravitational force a universal constant known as Gravitational constant is used. Electrical force is very much greater than gravitational force.

From Gauss's Law, Electric Field inside is 0, and it's electric flux is equal to Qenclosed/Eo, where Eo is the electric vacuum permittivity constant. Also, outside of the sphere, it could be treated as a point charge, where the point lies at the center of the shell and has a charge equal to the total charge of the shell.

In a conductor - only if the field is moving, thus changing.
