I can see Thysa/Bixdo/Casbit/Joroba being brandable. If you manage to snag a startup interested enough in that name, i would thinkg mid to high $xxx
UnityUp could be a community/tutorial site for the Unity platform (game-design).
Costaz could be a travel affiliate for the Spanish coast (Costa Brave/Del Sol/ ...).
Both might hold high $ xxx to low $xxxx value once developed
As for uaeFarms/X20X, I don't see the value
