I am leary to incourage anyone to try something that you cant see all angles of.
The tree in pic09 (loaded tree holdin up leaner) that some one is standing in front of has weak attached high v tri-dominent stems and looks to have some rot damage up there too, so I would not climb it. The (2) large up right Cotton woods guessing 36"-40" ones are on edge of the creek and have erroded roots with all the wieght on the creek side, I would not suggest to climb them.
I was looking at the pine with the top out of it, Can you rig the leaners to the base of pine through a arborist block and back to the large up right CW and use a 5:1 or a GWRS leave it slack when you make sallow face knotch toward the pine ,small leaner first for practice, this aint ax men, then seperatly rig the larger hung up one, use a shallow face cut and go up from center of face cut at least 10% of wood diameter for the back cut.
Leave about 15% holding wood then when you are clear load or help load riggiing to pull tree out with the 5:1 or winch it if you have the GWRS.
Dont cut through the holding wood. Use the rigging to pull it down and out and the holding wood will give mid fall,dont trust cotton woods,
