'the' and nationalities

Hello,

I know that sometimes we can use 'the', for example 'the British'. Sometimes we need to use 'the' + adjective + s..., for example the Americans.

Are my nouns ok?

1. the British
2. the Irish
3. the Greeks
4. the Koreans
5. the Spanish
6. the French
7. the Japaneese
8. the Germans
9. the Chineese
10. the Canadians
11. the Swiss
12. the Americans
13. the Dutch
14. the Polish

Would be very grateful for your help.

Thank you!

Kind regards,

Coincidence.
