Yes, at least the first and third pictures are clearly sunscald, from leaves that aren't used to so much direct sun. That is not serious. Those leaves will never recover, but the new ones that emerge will be adapted to the sun and will do fine. As imafan said, the prevention to that would be better hardening off, more gradual exposure to the sun.
I can't really tell too much wrong with the others, perhaps just a bit of transplant shock.
