The first one looks like it is an ESP01 stuck in a bigger board.
So have a look at the used flash chip to know how big it is. (probably 1 MB, but can also be less)
If it says PUYA, use the PUYA build.
It has a micro USB connector so I guess you may connect it to a PC and it will identify as a serial adapter.
Try to find what pin or button connects to GPIO 0 and ground that one to boot into flash mode.

The second one looks more useful.
An ESP12F has 4 MB flash.
I would try connecting the USB connector closest to the ESP module to see if it shows up as a serial port.
Also try to find out what connects to GPIO-0.

I know the second one and it's easy to flash it with the ESPFlash-Tool included in the download-Zip. Take the esp8266 4MB bin. But you have to connect the PC to the lower USB-port, the pc recognizes it as a USB to serial adapter. You don't have to press a button to flash the board. After flashing you can disconnect the lower board if you don't need it and use the usb port beside the esp chip for power supply.
