Yes. I tried for example, to remove this middle resistor, and I found the voltage between the points that connect R5 is 3,3V. Could I just add the resistor again and appy Ohms law on it? (3.3 = 1k*I)Have you worked with Kirchoffs' laws?
Not unless you find the Thevenin (or Norton) equivalent circuit and use that. The reason is that inserting the middle resistor back in will change the voltage at the points it connects to.Yes.

The biggest issue in the moment is to redraw this circuit since this middle resistor is hard to redraw for me.
