my first delivery was c-section..... was it possible to have normal delivery in next pregnancy

It will depend on ur body n present situation .Also ur doctor will tell u about this as she knows ur condition

How many years since the c section.?? Depending upon the situation and progress of pregnancy plus the time interval between both the pregnancies your doctor will decide ..
If all is well normal delivery is possible..

My first baby is 2 years 8 month and now I am planning for next

Hi yes now you can try for normal delivery. If everything is normal in pregnancy you try.
