I would like to know how to say "Hello my friends, How are we all today in German, Spanish, Dutch and French. Can anyone help please. Much appreciated xx
French: Bonjour, mes amis. Comment ca va aujourd'hui? (or just "ca va?" if you know them well)
German: Guten tag meine freunden. Wie geht es ihnen heute? (Or just wie geht's).
One thought: unless they really are at least acquaintances, fellow nationals and foreigners may find it uncomfortably engatiating/posy to hear someone make an inappropriately overt statement. Therefore, including "friends" might be better dropped in favour of the non-specific casual (but no less friendly) greeting.
