electric force
In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart.
It depends on what the charge is on both of the objects. If object 'A' is negative and object 'B' is negative, the two will repel or move away from each other. This is the same if both 'A' and 'B' are positive. However, if one is positive and one is negative, then the two will attract, or move closer.
No. It can exert a much weaker force on neutral objects, due to an induced separation of charges - that is, the charged object will cause a separation of charges in the uncharged object, thus creating an electric dipole.

That would be "Gravity".
Gravitational Forces
Either an attractive or repelling electrical force. It depends on what the charges of the objects are.
yes. same forces repel each other and opposite forces attract.
Yes, it's true. They interact via gauge particles called photons, which are the force carriers for the electromagnetic force.
