On previous ZF gearboxes the two diffs (1 and 4 in your image) use a single diff oil reservoir whilst the gearbox core (items 2 & 3) again uses its own centre reservoir.

As to the fluids themselves I've not seen a ZF 8HP gearbox myself so I can only go off what the general internet has said so take that into account -

Gearbox - ZF LifeGuard 8
Diff - 75W-90 but so many different types that picking one is almost impossible (with/without additives etc).
