There is a very subtle nuance between "all" and "every". Imagine 50 people.
"All the people are happy." This emphasizes that the people form a collective group. It makes me think of the people as a group, not as 50 separate individuals.
"Every person is happy." This emphasizes that we are talking about the people separately, one by one. It makes me think of the people as 50 distinct individuals who are happy.
"ever" generally means "at any time". "Have you ever been to Moscow?" = At any time in your life have you been to Moscow?
"never" means "at no time". "never" told us that something has not happened, or will not happen: Examples: "I have never visited China." "I will never go to the Moon."
In the following case, "ever" can mean the same thing as "never". When "ever" is used with with a negative word, than "negative word + ever" can equal "never". Examples: "He won't ever learn to speak Portuguese." = "He will never learn to speak Portuguese." "Don't ever say that again" = "Never say that again."
