Hi!
From my knowledge the hardware test, you have to do it without flash or other chip connected.
All 4 buffers have to be replaced! The replace buffers have to be marked with BU245 (please check)
For the third picture attached the test results show that you don't have on your PC USB port +5V, you have only +4.82V, that is OK for your programer to work fine.

The message before test is clear. You don't receive this message?

As Pityu mentioned hardware test should be done without any chips connected (it's very important!). When you do hardware test with chip connected then it is doing short circuit and drain high current.
