The manned type in the first picture,to my opinion is the Hanneton II.
In the second picture in the upper left is the BTZ 411-01, upper right
probably the BTZ 412 (without take-off booster), in the lower left is the
BTZ 525-12 (see pictre from Flugwelt 5/1957) and in the lower right
the BTZ 412-01 with and without booster.
