Well first of all your answers are not right to what the questions are asking. For instance, in the first one you have to have do the following steps...
1) Get color number from user
2) Open file
3) Read Line
4) Does person have color hair matching user input?
5) If yes, print name
6) Read next Line
7) Close file
The nassi would then look like the one below. Notice that they are not asking you to display the hair color, they are asking you to display the people with that hair color they chose.

I will leave the second one up to you. You can use the first one as an example. Remember that these are to show the structure of the program, so don't try to immediately jump to code. Think of the steps. It is like pseudocode but graphically.
Enjoy!
