IMO first address the Edison yellow bulbs in the kitchen they skew colors big time. I think a chandeleir type light is going to help but pot lights along the perimetr and maybe a an arc lamp since lighting needs to be at different levels and since

How high are those ceilings? To me they don't look high enough for anything that hangs down too much, so I'm thinking semi-flush. The art is too small for over that credenza.

If all of the spaces are open to each other, I would put the same light as you have in picture #3 (TV room). Othewise, you'll have the pendants in the kitchen, the existing light in the TV area, and then a 3rd "statement" light. The floor lamp you already have in the corner appears to have a similar shade, so it might tie everything in nicely.
