You logic is somewhat flawed. A libel case does not prove that the paper dealt in misinformation, even if they lost a case. It simply means that a court for one reason or another ordered that they pay a party money, OR that they chose to settle with a given party rather than go through a lengthy legal process.
You're first link
may be legitimate (though if it were I would think it would be easier to find information about this case), but a quick search of the name of the man in question reveals that there was widespread misreporting on Mohamed el Guerbouzi. The
BBC,
ABC, and
a number of other media sources made apologies to Mohamed el Guerbouzi along with
The Sun. Clearly there was something going on regarding suspicion of this individual. To propose that The Sun had uniquely and wrongfully accused him is misleading to say the least.
We can go on. Your second link simply states "404 - page not found". The third one has a somewhat unorthodox source though it is cited. Once again, the result of a libel case does not equal deliberate publication of misinformation or even publication of misinformation. It simply informs us of the result of a lawsuit. It's a sad fact of life that two different courts can arrive at two different conclusions regarding the same case, hence the neither of the libel cases you present conclusively demonstrate that The Sun was inaccurate. (As a side note, I saw the event referred to in the third link live

. I can't read lips, hence I can not report on the accuracy of the claims. )
We can go on about your claims if you want to. Their are more holes in the logic of the post I quoted that I could write about but in the interest of saving time I'm not going to address them unless someone here insists. There was also an implicit suggestion that all of the media sources suggested trace back to The Sun. The Fox article does cite The Sun as it's source. If the Telegraph is in fact owned by the same people as The Sun we could discount this as well, but there is no indication that the other two use the Sun as a source. Quoting an interview reported in another newspaper does not indicate that that newspaper is the sole source of information.
While no source is perfect, I see nothing which indicates that The Sun is a generally unreliable source. If anything, the findings here indicate that The Sun is held in some esteem by other publications which are as varied in nature as Fox and the BBC.
I'll leave you all with a page linking to some of the many media outlets which have covered
this story. Though I'm not familiar with all of the sources and some of them do appear to be duplicates (as is the case with all online media) there are a variety of reports on this subject.
