Answer: Hello mate!
The first question:
"Quien es la maestra?"
means "who is the teacher?" the answer here would be the name of your teacher, suppose that is Julia; so:
¿Quién es la maestra?
En la clase de espáñol la maestra es Julia.
¿Qué necesitas para la clase de español?
This means; "what things do you need for the Spanish class?"
here you need to do a list of 4 objects that you need in Spanish class:
For example, a pencil, a notebook, a Spanish textbook, and an eraser
where pencil in spanish is "lapiz", notebook is "cuaderno", spanish textbook is "libro de español", and eraser is "borrador".
then the answer is:
En la clase de español, necesito un lapiz, un cuaderno, el libro de español y un borrador.
Where I included the articles "un" that means "a"
"un lapiz" = "a pencil"
"el" that means "the"
"el libro de español" = "the Spanish textbook"
