You should include string 

#include <string>

then:

#include <iostream>
#include <string>   //<-------
using namespace std;
int main()
{
    string students[5][5] = { 
        {"Wayne","Val","Yolanda","Zeus","Xavier"},
        {"Yolanda","Wayne","Val","Xavier","Zeus"},
        {"Wayne","Zeus","Xavier","Wayne" ,"Zeus"},
        {"Val","Yolanda","Xavier","Wayne","Zeus"},
        {"Wayne","Yolanda","Val","Zeus","Xavier"}
    };

    for (int i = 0; i < 5; i++)
    {
        for (int j = 0; j < 5; j++)

        {
            cout << students[i][j] << " ";
        }
        cout << endl;
    }
    return 0;
}

You are initializing a single array of length 25. You have to do the init like so:

  string students[5][5]={ { "Wayne","Val","Yolanda","Zeus","Xavier" },
                          { "Yolanda","Wayne","Val","Xavier","Zeus" },
                          { "Wayne","Zeus","Xavier","Wayne","Zeus" },
                          { "Val","Yolanda","Xavier","Wayne","Zeus" },
                          { "Wayne","Yolanda","Val","Zeus","Xavier" } };

And, as François Andrieux mentionned in the comments, you should also include the proper header

#include <string>

because it defines the operator<< for strings.
