How should I input my names if I have two forenames and one last name, especially considering the German passport format?

When inputting names for visas or other official documents in Thailand, if your passport lists two forenames (e.g., Thomas David) and one last name, you should match the names exactly as they appear in the MRZ of your passport. Since the concept of a middle name does not exist in German passports, both forenames should be entered in the 'first name' field on forms, without separating the second forename into a 'middle name' field.
