Hey guys, we were asked to combine these two circuits in order to create a 3 way/4 way switch, my trials
have been unsuccesful so far, how do I approach this problem?

^not including the LEDs(This is a simple DPDT Relay)

I do not know what you are after, but 1V will not light a led and will have even less chance with two in series.

Don't mind the voltage, we are only after the correct circuit flow rather than an accurate simulation. (also as stated previously, those two LEDs are to be ignored since they won't be used anymore)

Furthermore, our target is to make a 3 way/ 4 way switch to control a bulb using one DPDT relay and two SPDT switches based on the configurations above.

If I'm not mistaken, it's based on this:
4-way-switch-1.png
The lamp will also be on if you move the 3-way switch on the left side to connect the movable arm to the upper contact.
Each of three switches has two positions, so all three together have a total of eight possible positions, four of which you have diagrammed above. For half of the eight positions the light will be on and for the other half it will be off. If you replace the 4-way switch with a DPDT relay, will that not accomplish your objective?
