As shown in the picture, please ask a Feng Shui master to see if the layout of the house is suitable for Feng Shui. Ask the master for advice.
I don’t know if you can see it if I tell you now.
The pictures you draw are very professional and can be understood at a glance.
According to the order of your questions, express your views, and it will be considered as an answer to your question.
1. The overall layout of the second floor is good. You can consider some local adjustments:
① It is better to use the north wall as a video wall so that there is no conflict with the south window of the living room.
② Place the sofa closer to the south wall. Depending on the situation, consider that the distance from the south wall is about 400 to 500 mm. Of course the sofa has to be turned.
③The air conditioner and refrigerator swap places, that is, the refrigerator is placed on the north wall and the air conditioner is installed on the south wall.
2. I don’t pay attention to Feng Shui. If I consider Feng Shui, the door on the second floor has something to do with Feng Shui and has nothing to do with the first floor. There is no problem with the position and opening direction of the second floor door.
3. It is recommended that you install a 2.0*1.1 door on the first floor or both doors are 2.0*1.2. The wider door on the second floor is easier to carry furniture, electrical appliances and other items.
No other issues.
Wish you a peaceful life.
