launchd jobs exit status -44
Solution 1:
The first column displays the PID of the job if it is running. The second column displays the last exit status of the job.
If the number in this column is negative, it represents the negative of the signal which stopped the job. Thus, "-15" would indicate that the job was terminated with SIGTERM.
Those can be either Unix Signals and/or BSD Signals.
man sigaction tells about every Signal possibilities.
man signal list their codes.
I have looked inside the source code of launchctl.c and I found it can also return any of these codes:

Code -44 is "Socket not supported" and looking at the processes you listed, all that have -44 are related to internet and/or iCloud stuff. Things that may return -44 while either on sleep mode or while you are disconnected from internet, or some similar situation.
