Hello guys, can this computer be upgraded with an AMD DX5 133mhz Cpu?

Hard to say, Am5x86 needs 3,3V voltage and I don't see voltage regulator on the motherboard from the photos.

I think that chipset shouldn't be an issue with a 5x86, though a BIOS update might be needed. If there isn't a 3.3V regulator on the board, you could get the 486 Socket Blaster from Scrap Computing to be able to safely use a 3.3V 5x86:
