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.
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.
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.
anions (negatively charged objects) repel cations (positively charged objects)

That would be "Gravity".

Gravitational Forces
They repel, same with two negatively charged objects
No, because force isn't something you "have". You can have momentum, or velocity, or energy, or acceleration, but you can't "have" a force - you exert a force on something else. Ocean currents have momentum/kinetic energy, and so they do exert a force on the water around them, the air above them, and any other objects in them.
