Hello,
What is the “status” column, and why I have “unknow?”

The TLE format specifies a flag that can be used for indicating the status of a satellite. You have unknown in it because that is what the TLE file specifies. I have never seen any other status in a TLE file, so it is practically useless.

Thank you Alex for information.
Actually, it looks like NOAA 15, 18, and 19 have statuses in their data 
Hi Alex,
Yes, I can see backup/statut. It is dommage that this parameters is not updated currently.
Update: where I can find the statut in TLE parameters ?
