Question

How many lines of force start from a unit charge ?

Answer 1

As many as you want. The are used only to provide an impression of the field strength and direction at any point. The only requirement is that these lines always begin on a positive charge and end on a negative charge, though often the negative charge is infinitely far away, so that we only present the positive charge in a pictorial.
