And thirdly when we are in periods can we stay my room which I am going to make masjid, as women in menstruation cannot enter masjids so please suggest!

It is mustahab to specify a place in one’s home for worship.
قوله فى مسجد بيتما وهوالمعد لصلاتها الذى يندب لها ولكل أحد اتخاذه كما فى البزارية . نهر . و مقتضاه أنه يندب الرجل أيضاً أن يخصص موضعاً من بيته لصلاته النافلة (شامى: 3/429)
You may fix one corner of your room for prayer etc rather it is mustahab. However, the place shall not carry the ruling of Shariah masjid; hence it shall be lawful for you to eat, drink, sleep and stay in the state of haiz in that room.
Allah knows Best!
