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.

As for the "unknowns" in the second picture I've seen the same information pretty much word for word translated from a French site
(IIRC) where the pictured vehicles are identified as missiles:
http://www.secretprojects.co.uk/forum/index.php/topic,4584.0/highlight,btz.html )
The one at top left is an anti-tank guided missile, the one at top right is the "top" of the surface-to-air ramjet missile pictured at
bottom right and the bottom left is another anti-aircraft missile configuration.

Here is the first page (teaser-page) for an AIAA article from 2002:
http://pdf.aiaa.org/preview/CDReadyMBIPL02_686/PV2002_5978.pdf

I may have posted this before but here are plans for building your own... Model that is:
http://jetex.org/models/plans/plans-misc/article-plan-coccinellida-am-5611.html

Page two of this article has a listing of some of the proposed vehicles:

First picture is not BTZ design, it's artist's impression of SNECMA Coleoptere. Second one is credited as BTZ Charançon (Weevil) and third one as BTZ Bruche (BTZ 527).

BTZ is the acronym for Bureau Technique Zborowski. Helmut Philip von Zborowski was a significant figure in early rocket and jet engine development. A contemporary of Werner von Braun, Zborowski worked on rocket and jet development for BMW during World War II, afterwards going to France and serving as a research engineer for the Société d'Etudes de la Propulsion par Réaction (SEPR). Zborowski later founded his own company, Bureau Technique Zborowski, which contributed significantly to the SNECMA C450 Coléoptère design.

BTZ was Bureau Technique Zborowski.
Helmut Graf von Zborowski was an Austrian aristocrat turned SS officer, who worked on the Walther rocket engine and other last-ditch weapons at the end of WW2. He was captured by the French.

The BTZ was created to get hold of his technical knowledge and continue his research, while keeping him more-or-less incommunicado in a castle near Paris to avoid the embarrassment of his unsavory past.

Edit: oops, I didn't see circle-5's post

yikes. The name had caught my attention a looooong time ago, in 1996 when I heard of the Coleoptere for the first time (well, second time after Tintin's Dan Cooper "Le mur du silence")
I ignored that the guy was a nazi SOB. I thought he was Polish.
Well, now I understand better the entire Coleoptere bizareness. It was a late offspring of the Luft'46 Wunderwaffen ! And it did not worked too well, the poor pilot paid a high price to the crash in 1959.
