Only judging from your pictures and without dimensions of the room nor furniture, here's the layout I suggest.

In the entrance place a small table and mirror. Move the 2 chairs against the wall to face the sofa. Place a TV cabinet along the wall where the chairs were. Hang a semi-flush light.

I would enclose the refrigerator with cabinetry (2 side panels with cabinet above refrigerator - make it the same height as other cabinets in the kitchen area). Centre the dining table and hang a chandelier. You should have room for a sideboard on the same wall as the refrigerator leaving a passage way along the other wall.
