You need use extrude with loft or extrude with boundry. You will draw in a sketch and then second. After these two you will use extrude with loft from one to other.This is the part 1(i noted in the picture). The second is that you will create a plane at bottom. In that plane create the part i noted as 2. The third will be drawn in the backplane of 1 and after that you can use linear pattern to do second of 2.(or you can use mirror but then you need a plane more)
