Door

We don't any reference from the Best Knowledgeable who are the Prophet Muhammad (SAWA) and his holy Progeny (AS) about such claims. People are free to place their doors and windows as they can or wish as far as it does not harm their neighbors and other people. Vaastu claims might be influenced by certain cultural factors in certain areas. It can not be correct always and every where.

Muslim should avoid taking thoughts or ideas from non Muslims unless it is in accordance of the teachings of the Prophet (SAWA) and Ahlul Bayt (AS).

Wassalam.

The attackers wanted to start a fight among Muslims, while Imam Ali (AS) was following the orders of the Prophet (SAWA) not to fight because fighting them will lead to civil war among Muslims which will weaken the Muslim society and the religion of Islam which was facing many enemies from non believers and hypocrites. Imam Ali (AS) did not fight against them for very important reason which is obeying the order of the Prophet (SAWA) to avoid civil war.

It is recommended to always face Qibla while sitting, eating, resting, reading, etc except when you are in the toilet then it becomes Haraam to face Qibla.

If you have the option, it is good to make the entrance door facing Qibla as well.
