Theres possibly something up with this third party repo.
I dont know anything about it, so I couldnt say.
You need to handle all of these.

(ex; sudo pacman -Syu meld && DIFFPROG=meld pacdiff -s)
This repo no longer exists.
This would be reflected in your pacman.conf.pacnew.
These should be gone.
Is there a reason for this on a plasma install?
Actually it doesnt exist in the repos or the AUR.
Which probably means it shouldnt be on your system.
This is an odd one … are you using openrc somehow?
This doesnt exist in the repos or the AUR and the version is rather old in comparison to systemd.
In general you have a good number of AUR packages … which is not necessarily a problem, but I wonder if they are all needed … and if they are all updated.
