Some help:
#21 - design studio.
#26 - production car, not obscure at all. Afaik, this manufacturer had different company name previously and used this badge for their cars. I cannot guarantee they still use this logo.
#32 - this car has different badge now since the company behind it is different.
#35 - probably the hardest one. I think this car never existed in reality.
#36 - model name is visible in the logo.
