Correct. There are also tribal/regional languages in Pakistan such as Sindh, etc. However, English is widely spoken as well.
As for the names, they may have SEO value, and may even receive natural traffic from Pakistanis, however be careful about what type/material of names you register, as forms of gambling, adult material, etc. are all staunchly prohibited in Pakistan.
