Dragin, such information is difficult to find in the public domain, added to the fact that every manufacturer claims to have IPR on their own vehicle!
Nonetheless:
Almost every pickup (the kind you are referring to, i.e. excluding van-based ones) on the Chinese market is based off the Isuzu TF's platform or an improvement thereof. This is apparent by their wheelbases which are either 3025 mm or 3380 mm. They may sport different bodies, but a look at the wheelbase dimension gives them away. Moreover, many of the newer bodies, irrespective of front ends, are copies of the 1st-gen. D-Max.
Talking of independent designs, I can list:
BAW Zhanqi pickups (BJ2032H)
BAW Ruiling (007-based)
Dongfeng Fengdu New Rich (though Nissan may have had a hand in this)
Great Wall Wingle 6 (previous Wingles 3 and 5 are believed to be related to the D-Max)
Huanghai N1/N1S
Huanghai N2
JMC Vigor
Leopaard CT5 (wheelbase is 3380 mm - coincidence?)
ZXAuto Tiger series (Grand/Little/export)
and the Foday Xiongshi F22 and Foton Tunland, as mentioned by you.
The Huanghai Plutus Luxury, JAC Ruichi Zhengtu, Kama KMC1032 and Kawei K1 are actually variations of the same truck, with vastly different fronts, but essentially the same 5.6-m body and 3500 mm wheelbase. I am not sure of the origin of this vehicle.
