I thought this is meant who is she you don't say who is this you would say what is this!
Ahmad, I am English, and strange as it may seem, we do say "who is this?" referring to a person! Also, it would help if you used punctuation. Is it not customary in Arabic?
Over half of the native Arab speakers that I converse with on HelloTalk do not use punctuation in either English or Arabic.
هاتف جديد مَن هٰذِهِ؟
Who is it = good english
That will be من ھو؟
