The layouts didn't get attached, try saving as 'jpeg' files.

#1 is the only one that works with your doorways. But I would rethink the sectional pieces which look too large. You will need at least a floor lamp. Your table/chairs looks narrow in relation to your sectional - is it to scale in the drawing? You may not have enough room. I would use a sofa against the wall and two chairs on either end facing toward each other.

no matter fan is far away from dining just add little bit extra rod to give it fall from ceiling from dining top 4' gap is enough for ceiling drop lights you can get these online or ikea hope it helps
