Identifying some East German badges and patches

[AllesIstVorbei]

I recently acquired these East German badges and patches.

Does anyone have any idea what they might have been awarded for?

Nos 1 & 2 are both Bundeswehr. 1 is badge for Bundesmarine U-Boot personnel and 2 is sleeve patch for Luftwaffe communications technical personnel.
Nos 4 & 6 aren't East German either. 4 looks American, but I'll leave identification of them to others.

Actually 4 looks like Deutsche Reichsbahn (railway), but unsure whether TR or DDR

Ah, thank you cvrwdvr! After doing a bit of research it seems as though you are right.

I think it is TR, but I might be wrong.
