Can I apply for HK Visa in Sri Lanka if I am working in Kuwait (w/ Sri Lankan Passport)

Hello, Mohamed, you can apply for it in Sri Lanka for both of you. The required documents include your passport and its photocopy, the application form with a recently-taken bareheaded color photo, financial supporting proof such as bank savings account or income certificate etc, transportation arrangement such as flight itinerary, as well as your travel plan to HK.
