1) He can't read or write well either
2) He can't read well or write well either.
Which one is correct?
Can I use 'well' two times in one sentence? or should I use ' well' only once?
As an NES but not a teacher:
Yes. I would try to minimise using words twice in a sentence.
I would probably have said:
"He can't read or write [English] very well."
