I see 7 hoses, so you have an open center valve with PB.
The pump hose goes to the IN port of the loader valve. That is the hose coming into the valve from the right side of the second pic.
The PB hose is the hose connected to the left side of valve with green markings.
The OUT hose goes to a return line.
The PB hose goes to the mid or back for a remote valve or the 3pt.
You then have two work port hoses for one set of cylinders, and another two work ports for the other set of cylinders.
You have to be careful about using QD's on hyd lines, if one set of QD's is disconnected, the pump flow will cause a valve to go into relief, or cause big problems..
You can work out where certain hoses go, by removing the QD, and watching for the flow when you flip a lever.
If there is a hose on the pump, and the engine is running, there is always fluid flowing through the hose, and the fluid either goes to a hyd block or the IN port of the loader valve.
If the IN hose is connected correctly, and all levers are in neutral, there will be flow out of the PB port, and that hose should go to the remote valves or 3pt input.
If the cyl hose are connected correctly, when you pull the lift lever, both lift cyls should extend, and when you push the lever fwd or down, the lift cyl should retract.
Same with the curl, lever one way and cyl will extend and the other way the cyl will retract.
Exactly where a hoses goes on our particular tractor, just use logical deduction.
I see some color markers on some of the hoses that may have some meaning.
