Name correction in my 10th and 12th class certificate

Hello Sir. I have cleared 10th in 2015 and 12th in 2017. In my 12th class certificate, the name of my father is incorrect. It is TRILOK CHAND , but the correct name is TRILOCHAN. Also in 10th certificate name of my father is TRILOK CHAND and name of my mother is NIRAMALA.But the correct names of my father and mother are TRILOCHAN and NIRMALA, which are in their all ID proofs. as well as my 5th class of records my father and mother name are wrong as above and i applied in my primary school for name correction in 5th class records but school not allow to correct my father and mother name and they say there is no power to correction of name in 5th class records and this reason my fathers name wrongly mention in my 12th class school leaving certificate so i cant apply to CBSE board for correction of name because board demanding school leaving certificate and admission form fill at the time admission and I want to correct their names in both documents. Please tell me the solution.
