well that may be what it is, a bad battery
but there are other causes for the DTC 168-4 also
alternator failure
operation cycle too short to charge battery
Quiescent current draw too high during truck off time

As for the other codes
DTC 190-4 not in the DTC code chart

DTC 524213-3 Horn Alarm Output Driver OORH
cause
Horn output driver short to battery

DTC 524263-1 Uncommanded Power Down
cause
VSM Failure

Now of course a defective battery may trigger many codes due to the erratic voltage it may be supplying but i would certainly not ignore these other codes if the battery is found to actually be the problem and replaced.

I would try and charge the battery, check it, load test it
if pass...then reinstall it and clear codes and run truck to see if any codes return.

if battery fails then replace battery, clear codes, run truck and monitor it.
