"Wie heißt sie?" means "What's her name?" in English. But maybe you meant "Wie heißen Sie?" This is the formal way to address someone we haven't met so far or a person of great respect.
sie sind wie alt = how old are they Sie sind wie alt = how old are you n.b. the difference is in the capitalisation of the word Sie/sie
The answer to "Wie heißt sie?" (what is her name?) would be "Sie heißt...." (her name is...)
Whats her name
how does she look or what does she look like
"Will sie sehen wie ein Kind" without any context means "want to see her/them like a child."
Sind sie wie alt? makes no sense whatsoever in German. You could either askWie alt sind sie/Sie = how old are they/yousie/Sie sind wie alt = how old are they/you orthey/you are how old
Wie heißen Sie? means what is your name? (lit. what are you called?)
Schrecklich wie über Sie cannot be translated sensibly without the proper context. As is stands it translates literally as terrible how over youPutting it into the context of a full sentence will hopefully offer a more meaningful translation:Es ist schrecklich wie über Sie geredet wird = Its terrible the way people talk about you
How old are you? transaltes as Wie alt bist Du? (informal) or Wie alt sind Sie?(formal).
Asking how old some one is the question would be :- "Wie alt sind Sie?" or to a child "Wie alt bist du ?"When asked by an official to prove your age he or she would say :-"Zeigen Sie mir wie alt Sie sind" or "Zeigen Sie mir Ihren Ausweis"
Wie heisst du? oder Wie heissen Sie? Or: Wie ist Ihr Name?
"how dare you"
