The tape was made by a PDP-11 system running RT-11. This manual may
help a little:
http://bitsavers.org/pdf/dec/pdp11/rt11/v5.6_Aug91/AA-PD6PA-TC_RT-11_Volume_and_File_Formats_Manual_Aug91.pdf
TL;DR - This tape was written by just copying disk files to it, so the
files which contain actual data are just images of the disk files.
File 5 - this looks like a file system image.
File 8 - appears to be some sort of archiver output, but while the .ARC
extension might lead you to suspect the old CP/M - MSDOS ARC program was
responsible, that doesn't appear to be the case.
File 11 - this is an older format tarball.
