This should assemble, so I am puzzled by the earlier issue.
The event counters (13922, 13917, 13926, 13917) do show some lost writes - they should all be 13926.
Maybe try this variation:
mdadm --assemble --really-force /dev/md127 /dev/sda3 /dev/sdb3 /dev/sdc3 /dev/sdd3
Hallo Markuzz
Ignoring all warnings have lead to the end of this volume (including your data) started. Two disks were removed back in April, or some hardware issue caused to drop the channels with the ST3000DM001. Even before, the Toshiba and the Hitachi drive reported high spin retry counts, indicating a possible coming up failure. Read that complete message what your ReadyNAS indicated several times before.
Don't know if this RN104 will now no longer willing to take new HDDs in slot #1 and slot #3, certainly the HDD in channel #4 was lost before - there is went the only redundancy.
Not sue what you expect now.
