Question

why didn't she dare to go home? how did her hands become numb?

Answer 1

There was snow on the ground and her clothes were inadequate for the cold weather, she didn't even have shoes on her feet. She was very poor. So her hands turned numb from the freezing cold.

She couldn't go home as nobody was purchasing the matches and she could not make any money. If returned empty-handed, her father would beat her.

Answer 2

She did not dare to go home because she had sold no matches and earned not a single penny. She knew her father would surely beat her. Moreover it was cold at home because the roof had holes in it. Her hand became numb with cold.
