Thank you François for your answer.
now the drives are connected to an hp workstation - Intel® Xeon(R) CPU
E5430 @ 2.66GHz × 4
I have a dual boot on machine with win 7 ultimate and Ubuntu 18.04.1 LTS
I think I put my drives in the correct  order based on the logs from
my NAS and this is the point were I am in this moment

The order doesn't really matter. The disks have some metadata that will tell linux what their position within the array is. So Linux won't be looking at the disk order but will just look at this data in the superblock.

At this point, I would guess that your md0 array is probably the NAS operating system. It is quite typical for NAS devices to install their OS on a raid1 volume that spreads on all the disks that are installed. My Synology NAS does this too. So, there's probably nothing interesting there. So the focus would have to be on the other volumes I think. More specifically, your data is likely to be in the md127  volume due to its much larger size.

Can you please post the output of the following commands:
mdadm --examine /dev/sdc3
mdadm --examine /dev/sdb3
mdadm --examine /dev/sdd3
mdadm --examine /dev/sde3

Also, at this point, do *not* run any command to re-assemble your raid volumes. First we need to properly understand what those arrays are for and in which precise state they are. Let's also hope your windows software didn't harm your data...
