My office is on the second floor, is it okay to put him above the door of the company

It's fine. Unless the toilet is not good on the roof of your own building, you don't commit taboos under your feet. There is also a saying that you will be very fat when you step on the toilet, which is a good thing. Of course, summer may be a little flavorful, and nothing else.

This is okay, our boss is on the second floor facing the balcony, which is better in the sun.

It is possible from the functional layout, and there is no restriction on this in the fire code, as long as the building meets the corresponding requirements for fire prevention, fire resistance, evacuation, etc., and the corresponding fire extinguishing and rescue, fire fighting and other facilities are configured.

Affecting health and financial luck, the five elements of the toilet belong to water, and it can be resolved by using wood to drain water, so it can be resolved by putting more green plants in the office.

There is a filing cabinet in the back, which is a backing, okay.
