.. or the Hanneton II, as the III should have a wider fuselage.
The others were more or less mentioned here :

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.
It takes a long time, before all mistakes are made ...

Three-view drawing of Bureau Technique Zborovski (BTZ) Hanneton III. Bureau Technique Zborovski was located in Brunoy, France.

Wood model of BTZ Hanneton III.

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:

Also from Le Fana 474;
And from that site;

In the 4th picture, the text says tthe name of the bird is BTZ Dragon.

http://aerospaceengines.blogspot.com.eg/2014/11/cdxl-la-version-francesa-de-vtol-de-los.html

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