Code #1

Observations

Passcode format is there, albeit with an invalid digits 1.

Code #2

Observations

The character set is rather limited for the length of the code, with {c,d,f,g,a,4,5,6,#}.
There are lots of repetitions or similarly structured blocks (either digit-letter or digit-#-letter.)

Code #3

Observations

We can see “five” and “one” backwards the code.
