The pics are too small for me to tell on the airmails, but both appear genuine and not CTOs.
But the cancels on the semipostals do not appear to be genuine postal use, although a genuine cancelling device was used. The problem with the stamps of that era are that genuine postal cancelling devices were stolen, and used to fake postally used stamps. That is the reason why so many of those values are italicized. Even a stamp on cover/piece does not necessarily prove genuine postal use. You must rely in part on the ink used to cancel the stamp, or other postal markings on the cover.
The majority of "used" German semipostals near the end of the war and reconstruction period are faked cancels.
