How is a house, bequeathed by a father to his mother and four daughters, to be divided among five women and seven men, and is a will for a house executed with witnesses?

Bequesting the father's house to the wife and daughters is a bequest to an heir and is forbidden. It is not enforceable unless the rest of the heirs agree, based on the hadith: "There is no bequest for an heir." Your brothers have the right to refuse it and take their full share. If any of the heirs do not permit the bequest, the house is divided among all heirs (including the wife) by one of the following methods: valuation, sale (to an outsider or one of the heirs), or mutual agreement.
