Well no, they weren't (with the exception of Hamas, and the only partial exception of Iran). It is true that they all tried to claim democratic legitimacy (which is I think your point), but I think that only highlights the (potential) power of expressed popular consent.

The question of democracy and underlying political culture is a hotly debated (perhaps THE most hotly debated) issue in the democratization literature. Certainly it helps a great deal if underlying cultural values support democracy—but the "third wave" of democratization suggested that it could also take root in societies with no prior history of democratic politics.

Yes, absolutely.

"Validity" is, to my mind, a social construct in politics. I believe that it is quite rare, possibly limited to the Anglo complex and, I think, Salic law, that a "law" that is invalid should be overthrown. I'm thinking about Magna Carta style right of revolt, and yet your first question seems to be predicated on the assumption that something like that exists. I think that most societies have a very different, starker, view of governments and laws.
I think the prevailing social practice in much of the world is not so much overturning laws, or the governments that made them, but rather simply ignoring them (or a passive-aggressive non-cooperation with government, in what James Scott called "everyday forms of resistance")--especially where the central government lacks the ability to enforce its legal writ.

I tend to think that democratic politics has a lot to do with boundaries of the acceptable and unacceptable, in which public attitudes, capabilities, perceived intentions, and the local balance of forces play a key role. Democracies tend to work when political entrpreneurs are unwilling or unable to contemplate using nondemocratic methods to achieve policy ends. Its kind of like successful nuclear deterrence
