Yes, I agree all are somewhat brandable.
My ideas for the names are as followed.
Yubdo: GEO name (city in Ethiopia known for mining Gold & Platinum.)
EthCoop: many different abbreviations are suitable
Ex.
Ethereum Cooperative
Tizaze: Means "Order" in Amharic
As far as monetizing the following names I think names are short, unique, brandable for right buyer...
