At least one if not two more companions.
I'd suggest restarting - it's early enough - (or going back to an earlier save) and having a little poke around in the hills above the crash site - you don't have to go far - and you should pick up one or two more people to help you out. 2vs 6 at that level is never going to end well without a lot of very lucky rolls unfortunately.
This... you have missed a couple companions. The "footprints" you mention in your post lead you to an unstable waypoint stone. Explore it. A party of 4 should be able to easily clear the ruins. Good luck!
