Answer:
The helpful people in Josef's story are Ruthie and his mother. This is because they are a constant support for Josef after he loses his father to his sudden mentality. Although he is alive, when his mother dances with him in the ballroom, he sees that she is still strong, and Ruthie is supporting Josef's mother, like Hana was dear to Mahmoud's mother.
The police officer was also a very dear character for saving Josef's father when he wanted to drown himself off the boat. I believe this character was Lito?
Hope this helps!
