So I hope I got some of these right.
[@Apollo13 had already posted: Guess these plains are all prototypes, the look similar to: Curtiss Helldiver, Bücker( maybe Zlin), Walrus, Vampire(this had actially a jet-engine) an the tail of the last one seems have to do with a Noratlas. I know, iknow, they are not but asking is for free... , i like this quiz. (what is the first price...)]

#4 SNCASO SO.8000 Narval
The SNCASO SO.8000 Narval (English:
Narwhal) was a French carrier-based strike fighter designed by Sud-Ouest in the late 1940s. The French Navy (Marine nationale) ordered two prototypes in 1946 and they made their maiden flights three years later. They were plagued by aerodynamic problems and unreliability issues with their piston engines. The aircraft proved to be slow, lacking in lateral and longitudinal stability and unsuitable for carrier operations; it did not enter production.
#5 Tachikawa Ki-94
The Tachikawa Ki-94 was a single-seat fighter-Interceptor aircraft project undertaken by the Tachikawa Aircraft Company and to be operated by the Imperial Japanese Army. The project refers to two aircraft designs: the Ki-94-I and the Ki-94-II, both of which did not advance beyond the mock-up and prototype stage respectively.
