Yes, electricity exists in discrete amounts that equal some whole number of electrons.
They have fixed energy values.
Quantized. (Number 4 if you are using what I think you are using.)
Digital quantized information and analog is just information. Like the letter "i" on your screen is digital and made up of a few pixels= quantized. The letter "i" drawn on a piece of paper is not quantized = analog.
It is quantised.

No. A quantized orbit means the energy is locked in as a constant. It would have to switch to a different orbit to emit energy.
Electrical charge is quantized. (negative in an electron, as an electron has exactly -1 fundamental unit of charge) The other two would be the energy levels in the atoms and the emitted energy.
A quantized condition refers to a specific state or value that is constrained to discrete or distinct levels, such as multiples of a minimum unit (quantum). In physics, quantized conditions often arise in systems that exhibit quantization of energy levels or other properties according to fundamental principles like quantum mechanics.

The electromagnetic spectrum provides evidence for quantized changes in energy levels of atoms. This is seen in the emission or absorption of specific discrete frequencies of light, which is a result of electrons jumping between quantized energy levels within the atom. This phenomenon is described by quantum mechanics.
