The rectangle around the light source is probably just an artifact of jpeg compression; you can see similar ones in the moon shots,
although not as definite, since those appear more out of focus.
It looks like you caught something legitimate, probably a fielball/meteor. Whatever it was, it was much bluer than the moon.
At first I suspected a reflection from your flash, as the light source is so much sharper than the moon in sun1/2/3. However, in sun5.jpg the camera
is focused on the background (compare to sun4.jpg, where the camera focused on the edge of the house's roof; also look closely at the clouds and the
phone wires), whereas in sun1/2/3/4 the camera focussed on the foreground. That means that whatever it was, it was probably at least as far away as
the utility poles, and possibly as distant -- or farther -- than the clouds.
Your camera exhibits a slight bit of astigmatism, about few degrees off the long axis, which makes it fairly easy to determine that lens flare appears
consistant, frame to frame. I mention that because the sun5 spot is elongated vertically, but not in the direction I would expect if it were caused
by lens aberations. That indicates the light source may have been in motion.
There are almost invisible clouds in sun4, which look backlit in sun5. As the two frames were shot only 2 seconds apart (that's what the jpeg
headers say, anyway ) and at the same exposure (5.8mm fl, ISO 250, .5 sec @ f2.8), I'd say something further than the clouds was glowing VERY
Finally, if you examine untouchedsun closely, the bright spot is saturated in the center, fades a bit, then flares back out to saturated around the
circumference before fading out completely. The only mechanism I know of to produce that effect is the diffraction rings around star images in
telescopes, but this is an inexpensive Fuji A350 -- no offense, I'm thinking of getting one for somebody for Christmas. An object seen by reflected
light may have a peculiar "edge-effect", but a digital camera should be immune to that. An object which glows from within (like the sun) exhibits a
distinctive appearance where the edge is much dimmer than the center, but it doesn't get brighter beyond that. But you can see the same effect in a
flame (or flaming object).
October was a good month for fireballs up this way:
and just about everywhere else:
Congratulations, Mayet, it seems you got a picture of an exploding fireball -- that's a rare occurance, indeed.

-- Exposures differ by around 400%. That alone would would explain the differences in the "rays".
--They were shot from different locations -- check the trees and utility poles in the distance.
-- Focus varies considerably between shots -- would also effect size of spot and appearance of "rays".
