ThanksThey are acting as rafter ties for that short wall so assuming it is bearing you cannot take them out with out some alternative to keeping the wall from being pushed out by the rafters.
Sorry, I totally missed your post. I thought I had notifications turned on.I'm sure by looking at that second picture if you can take them out or not. It's going to depend on how the rafters are attached to the top of both of the walls, the taller one in the short knee wall.
Following up on what carpdad said, there is no ventilation space going to the peak of your roof. It also looks like there are some areas that don't have any insulation. Also what's that structural member going horizontally? Is it a header over the entrance to this area?
