One will say: "Drishat Shalom" - דרישת שלום.
In modern Hebrew, it's meitav ha'ichulim (the "ch" is a rasping sound).
מיטב האיחוליםdash (ד״ש) or drishat shalom (דרישת שלו×)

groeten is the word for regards in Dutch. It is used to say respectfully someone.
Kind of depends on the context, but 'Nifla' is one way to say lovely in Hebrew. Another way is to just say that something is "Ya-feh"
the Hebrew word "eved" often translated as 'slave' actually refers to any kind of worker.
if you are talking about the use of the word "regards" in letters, it would be "bivracha" (בברכה), which means "with a blessing".
Regards, Kind regards, Best regards.
