If you have Navigation properties created over foreign keys in your database then there should be no problems in assignment. Set the detail entities to the navigation properties of their masters, like this pseudo code:
//Create an accData instance in some way
accData.PhnNumbers.Add(phnNumber);
accData.CntactData.Add(cntData);
//Load the FnclMaster in some way, for example,
FnclMaster master = db.FnclMasters.Where(it=>it.FnclprdIdCode == myCode && it.AccNo == myAccNo);
master.FnclDetails.Add(fnclDetail);
context.AddToAccDatas(accData);
context.SaveChanges();
