Are these sentences correct?
Oh, I never knew that she is my twin sister.
Oh, I have never known that she is my twin sister.
Oh, I had never known that she is my twin sister.Additional Details:Oh, I never knew that she was my twin sister.

If I changed IS to WAS, it would sound like her twin sister was dead, Am I right?

Answer

No, just because you use 'was' it doesn't imply she is dead and is no longer her twin. It is used in the past tense, so before she didn't know and now (in the present) she knows she is her twin sister. so 'oh, I never knew she was my twin sister' makes sense.
hope that helps.

Answer

All the forms you listed are correct. WAS indicates my twin sister is either not my twin sister anymore or has passed away. You are correct in your assumptions.

Answer

The first one is correct
