How many transition states are there in an electrophilic reaction?

If you're talking about an electrophillic addition reaction mechanism, there are two transition states.

There are many types of electrophilic reactions in chemistry. For the once covered in lecture, there are 2 steps.

In the electrophilic addition reaction there are two transition states since there are two steps. Each step correlates with a differing transition state. In the first transition state, the double bond breaks between two carbons, and the electrophile (ex.H-Br) attaches through a tentative bond with the carbon on one side of the broken double bond. This creates a carbocation on the other side of the bond, where in transition state 2, the Br- breaks and forms a bond with the carbocation. This leads into the final product where H and Br are now attached to the original structure, and there is no double bond present any longer within the molecule.
