1. Will not light - Without the wire, the light bulb will neither turn on nor off as the wires act as a path for the current to flow from the source to the light bulb. Unless some components are integrated with such.
2. Dimmer -Given the number of bulbs being used and only a single source (battery), the electricity demand would be greater in contrast to using lesser bulbs.

4. Will not light - Without the source, the light bulb would neither turn on nor off. Any electrical object needs a source to operate thus without the source no actions can be executed.
Note: Results may vary depending on what components are used. Since the light bulbs and batteries were not specified therefore I based it on my science project back in my elementary years. Specifically, AA batteries and miniature bulbs.
