No doubt there are many factors. Gasoline needs volatile components to promote ignition and burning, particularly when the engine is cold. It also needs to burn evenly so antiknock properties are important. Diesel needs to have a low autoignition temperature so that the heat of compression enables combustion. It so happens that heavier fractions suit. Jet fuel must resist low temperatures without solidifying or wax crystals forming. For safety reasons a low vapour pressure is also desirable.
Edited Comment: Wow! The below three respondents obviously do not know that gas turbines (essentially jet engines with extra power recovery turbine(s)) can be designed to run with equal power and efficiency on a wide range of fuels from gases to diesel. Octane rating has no relevance to diesels or jet engines.

Each is refined to a higher degree also known as octane level. Jet fuel has the highest octane since fighter jets need a high performance fuel. Diesel fuel is the least refined.

each have different ignition point..hence the main reason for being used in different engines..and also...their power differes ...jet fuel has the highest power compared with kerosene and petro; diesel or gasoline
burning rate is also different...
more fuel burnt in less time more is the power...

different octane levels, jet fuel has the highest
