Most of the time, in an object, its negative and positive charges are balanced, which makes it a neutrally-charged object. Sometimes, when some objects come into contact with other things, they gather more charges of one type. If there are more electrons, they are negatively-charged. If there are more protons, they are positively-charged. Because opposites attract, an object which is negatively-charged will attract another object which is positively-charged and vice versa.
Any "object" larger than elementary particles consists of positive and negative charges. If your object has a negative charge, it simply has more particles with a negative charge than particles with a positive charge.
To ground an object means to connect it through a conductor to the ground, or Earth. Grounding is a way to prevent an electric charge from building on an object, or to get rid of an electric charge.
Most waves are caused by a vibrating object. Electromagnetic waves may be caused by charged particles.

If an object is negatively charged, it has an excess of electrons. If it is positively charged, there are atoms which are short of electrons so you observe the positive charges of the atomic nuclei which are no longer balanced by the electrons that were normally in place.

In a electrostatically neutral object there are equal numbers of charged particles (electrons and protons).

That means that the object has more particles with a negative charge than particles with a positive charge (or the other way round).

-- They can if the gravitational force of attraction is greater than the electrostatic force of repulsion between them. -- They also can if they're connected by a rubber band that has been stretched. -- But if the only force between them is the electrostatic force due to their charges, then they must always repel, because their charges have the same sign.
In that case, the object will accelerate.
