That depends on what you consider a charge.
Electrons/protons?
Compute approx. number of molecules, multiply by 10 for positive or negative charges.
Water dipols?
Compute approx. number of molecules for positive or negative charges.
Ions/Anions? (Technically, this is not part of water, but salt solutions within it)
Don't know how many milligrams of salt there is in an average cup of water.
the object has to have more positive charges than negative charges.
Proteins become more soluble with increased positive or negative charges because they form more interactions with water molecules through electrostatic attractions. These charged residues can bind to water molecules, stabilizing the protein structure and increasing its solubility in aqueous environments.
No , an atom always has equal numbers of protons and electrons. If it has more charges of one kind than another is called an ion. Obviously this is caused by the number of protons and electrons compared to each other. If it has more positive charges, it has more protons than electrons, making it a positive ion. If it is a negative charge, it has more electrons than protons, it is a negative ion.
This would be called a CATION.
No, if a jar is already full of negative charges, adding more negative charges would result in repulsion among the charges and likely lead to discharge or redistribution of charges. The negative charges would try to move away from each other to minimize repulsion.
A charged object can have an unequal number of positive and negative charges, resulting in a net charge. An object with more positive charges than negative charges will have a positive net charge, and vice versa for negative charges.
the object has to have more positive charges than negative charges.
No, positive objects can contain a mix of positive and negative charges. For example, in an atom, the nucleus contains positive protons while the surrounding electron cloud contains negative electrons.

If an atom has 3 positive charges (protons) and 4 negative charges (electrons), the 3 positive charges would "cancel out" 3 negative charges, with one negative charge left over. So the atom would have a charge of -1.
This would be called a CATION.
The opposite of a negative charge is a positive charge. Positive charges have more protons than electrons, resulting in an overall positive charge.
An object that does not contain equal amounts of positive charge and negative charge is considered to be charged. It may have a net positive charge (if it has more positive charges) or a net negative charge (if it has more negative charges).
The water molecule has a partial negative and partial positive charge because it is a polar molecule. Electrostatic attraction between the partial negative and partial positive molecules gives the water molecule its partial charge.
No, if a jar is already full of negative charges, adding more negative charges would result in repulsion among the charges and likely lead to discharge or redistribution of charges. The negative charges would try to move away from each other to minimize repulsion.
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.
