The Green wires are going to be Voltage supply and then the other four are the four seperate coils.

The way you have it in your schematic isn't the same as how you have it wired up!

So it means I need to use Darlington array like the shown image?
it there a way directly connect it to arduino pin?

You can use 4  TIP122 transistors or  4  N channel MOSFETs.
You need external components with these.

However, for your 50 ohm stepper, drivers like ULN2004 or ULN2803 are small packages and easy to work with especially on bread boards.
