I just reread your posts. Am I reading this right? You have 4 quick connects on the right of the tractor and 2 on the left?
It is a bit difficult to answer general questions, because anyone could have done anything with the hydraulic system on that tractor. All couplings on the tractor SHOULD be female. All the ones on the loader should be male.
Doesn't your loader have 2 way cylinders? (down pressure) No hoses will be only "return" or "pressure", they could be either one, depending which way you are pushing the lever.
