I have 2 herniated discs at l4, l5 and s1 with annular tears. can it be fixed. if so, how? success rate? complications?

Depends.: Your question will need to be answered by someone who can see you directly and correlate the info between your exam and your studies. Should only be fixed if it is causing impingement of the nerve root with compatible symptoms. Otherwise the best treatment is medical - physical therapy, medications, etc.

Cannot "fix": Cant fix the tears. Treat the symptoms with therapy, rest, rarely surgery!
