Recognized 3 and Recognized 10 seem to be contiguous partitions.

Alternatively, 7, 12, 18 and 19 are also contiguous, as are 2, 5 and 15.

IMHO, DMDE's Partitions tab is a much better display format.

they are all potentially valid
the inodes and superblocks are spread across the drive
Each group is like a mini volume with its own superblock inode table and directory...
or not
they may be false
or partially initialized.
use ufs explorer

As long as the customer didn't create new partitions and format them, initialisation by Windows should only have touched the GPT metadata in sectors 0, 1, and 2 plus the backups at the end of the drive. Maybe you haven't been given the full story?

Solaris used a modified version of ufs.
The structure may not be recognized. 
I write my own parser to recover these. 
It's been a while since I have seen one.
