No - the sentence 'Had never been experience' is not a correct sentence.
The correct phrasing would be "B years' experience," indicating that the experience spans multiple years.

No, it should be past experience

No, "most unique" is not correct usage. "Unique" means one of a kind, so something is either unique or it is not: there cannot be different degrees of uniqueness, and something cannot be very unique or most unique. It is not uncommon to hear people say "very unique" or "most unique", but this is not correct. They should be using "unusual" if they want to use it with "very" or "most".
The second one a once-in-a-lifetime experience
The correct spelling is "experiment" (a test of a scientific hypothesis).
The correct spelling is 'experience'.
The correct spelling is experience.
