Electricity is the source of energy in a light bulb.

No, a bulb is not a source of energy. A bulb simply converts electrical energy into light energy. The electrical energy is usually provided by a power source, such as a battery or a power outlet.

No, a light bulb needs a closed circuit with a power source, such as a battery or electrical outlet, in order to light up. Simply connecting a wire to a light bulb without a power source will not allow it to light up.
The light bulb must be connected in a closed circuit with a power source, such as a battery or electrical outlet, for it to light up. This means that the positive terminal of the power source must be connected to the positive terminal of the light bulb, and the negative terminal of the power source must be connected to the negative terminal of the light bulb. This allows the flow of electricity to power the light bulb and make it light up.
Either, depending on the situation. If you look at it from far away, the light seems to come from a single direction, and can be simplified as a point-source. If you are very close, the light comes from different directions, and such a simplification is no longer correct.

Yes, that is a "conventional" source of light.
The bulb converts energy from the power source into light and heat. It is the load in the circuit.
To light a bulb, you typically need a power source (such as a battery or electrical outlet), a conductive material to connect the bulb to the power source (such as wires), and a functioning bulb itself. When these components are properly connected and the power is supplied, the bulb should light up.
A light bulb is not a source of electricity. It is a device used to harness electricity to provide light.
