You did a pretty good job expressing those concepts in English in your post. Sure, there's no single word for each of those expressions, but that only means they're not that popular in everyday usage.

If they were popular enough, we'd say: English does have words for those ideas! They're "feierabend" and "saudade".

Exactly the same as "gesundheit".

Thanks for the compliment, however I feel from the linguistic point of view, I explained them.

Expressing means there is a similar word.
