D1 mini - pin hole / track repair
No that I understand what you're trying to do (rather, what you have already done, as it appears from your images), no, you cannot simply bridge each pin to the pad it is next to. It seems that since you have already gone ahead and done the soldering, my answer is rather pointless, but I will go ahead and answer anyway for posterity's sake...

Your question could be easily answered by looking at the schematic: most of the pins have a 1:1 correspondence, except for ADC/A0 and power supply pins. From your images, it appears you have bypassed the ADC divider (not so bad), misconnected several GPIOs (16, 14, 12, 13, and 15), connected GPIO15 to GND (not good), and connected 5V to ground (very not good). If you have powered up the unit in this state, I suspect it will be very unhappy.

Additionally, as I can't tell which tracks have been lifted where, it's possible that vital circuitry has been disconnected from the pins. In short, scrap the board and start over. All in all, not a bad board to learn how to solder on, a $3 board isn't much of a loss. In the future, patience and reading the schematic are your friend.

Now, if you do want to try and repair it:

First, look at this schematic. This is the official schematic from Wemos, and hopefully matches your board (no guarantees though, that's the consequence of cheap dev boards).

From the schematic, here's how things are pinned out (with pinouts flipped where logical):

   JP2 |    ESP-12F    | JP1
------------------------------
   RST | RST        TX | TX
    A0 | ADC        RX | RX
GPIO16 | EN      GPIO5 | GPIO5
GPIO14 | GPIO16  GPIO4 | GPIO4
GPIO12 | GPIO14  GPIO0 | GPIO0
GPIO13 | GPIO12  GPIO2 | GPIO2
GPIO15 | GPIO13 GPIO15 | GND
   3V3 | 3V3       GND | +5V


From this diagram, you should be able to figure out what needs to be bridge to what. For the 5V pin, you'll have to either scrape the trace clean or wire it to the regulator input (although maybe you don't need the 5V pin). May also have to scrape for A0: A0 is different than ADC!
