The answer is your question is NO!
In most cases when aircraft are stuck by lighting which is a static charge it will take the path of least resistance. This means the flow of electrons will flow on the out side of the aircraft skin and discharge out the wing trailing edges, wing tips and elevators trailing edges. This is why if you look at the flight controls surfaces you will notice they have a bonding strap/wire from the main structure to the flight control to allow the flow of electrons to discharge.
On composite aircraft there is a fine mess aluminum screen imbedded in the lay-up just to transfer the electrons across the surface and out the static rods located on the trailing edges of the wing or flight control surface.
You can find more information on this subject by reading the following AC:
AC 23.1309-1C Equipment, systems, and installations in part 23 airplanes
The above is available on the FAA web site at http://www.faa.gov just type in the AC number or use any search engine and it should take you to it. Also Related Reading Material: A comprehensive discussion of lighting protection, with additional nonregulatory guidance information, is available in the current edition of FAA Report DOT/FAA/CT-89/22, "Aircraft Lightning Protection Handbook," dated September 1989. This document is available to the public through the National Technical Information Service, Springfield, VA 22161.
Appendix 3 of AC 20-136 defines total lightning environment, including the multiple stroke and multiple burst lightning environment to be used for test and analysis purposes in qualifying systems and equipment for lighting protection. AC 20-136 is proposed as a basis to use in demonstrating compliance with the lightning protection requirements, except for the multiple burst lightning environment that has been changed to agree with recommendations from the Society of Automotive Engineers (SAE) AE4L Committee, dated July 6, 1992. The multiple burst lightning environment that is defined in AC 20-136 has been changed from 24 bursts to 3 bursts and it is used mainly for test and analysis of system functional upset.

It depends. If two metal fuel lines are connected by a rubber hose and aren't bonded, I guess the lightning could jump the gap, burn the rubber, and ignite the fuel, but I've never heard of it happening.
Most aircraft are bonded to reduce radio noise, and to prevent damage to avionics, flight control bearings (they could be welded together by the arc) and composite panels when they are struck by lightning.
Even if lightning struck an unbonded fuel tank, it would just travel through the metal of the tank to where it was attached to the aircraft and exit, not affecting the fuel at all.

often whilst lightning hits an airplane, it the two motives none or little or no injury. extremely using layout of the airplane, the electrical powered cost of the lightning will in basic terms get performed ariund the cabin in the process the fuselage, and could bypass away on the trailing (rear) edges of the wings or different components. each and every now and then it will make a small get right of entry to and /or go out hollow interior the fuselage, and in uncommon ocations it may reason some injury to electric supllys isn't desirable grounded. Composit airplane that are IFR rated (waiting to fly in clouds) have steel wires that run in the process the fuselage to assist disperse the electrisity in basic terms like a common steel fuselage. Non-IFR rated composite airplane are maximum likelly to get intense injury from loghtning strike.

Aircraft of all types are frequently struck by lightning, this is factored into the construction.
The most danger is when planes are attempting to land, there by becoming an earth as they touch the ground.
Regulations state planes should avoid landing in thunder storms and divert to an alternative airfield.

If not bonded, There will be extensive damage. Explosion can occur but is unlikely however the end result may appear like an explosion of sorts occured. Remember how easily aluminum melts compared to the material we use for bonding jumpers!

I would say yes, but it would also depend on your qualification for an explosion.

no or they wouldn't spend the money to make them
