The fifth Manifesto can only be obtained after completing “Overgrowth” mission, this can be obtained once you have completed “A Dying Planet”. It is located in the middle of the second Roekaar Camp (where you found the Roekaar Research during Overgrowth) on top of a box (Img 4).
The sixth and final Manifesto can be found on a table (Img 5) in Thaldyr’s home. To gain access to Thaldyr’s home you need to start “Friend or Foe” which can be obtained by speaking to Jaal after Calling Evfra from the Tempest’s meeting room.
