Help in buying a new car

HI, I am planning to buy my 1st car and have never driven a car before and just joined a driving school. My thoughts are caught between 1> FIgo Trend Petrol 2>Baleno sigma petrol 3>Kuv 100 k4 pertol 4>Kwid Rxt. I might drive the car around 500 Km a month and occasionally might take it out station. Also do you think I should consider choosing a diesel car ?
