Have you tried opening all the files at once and using one string for each input file? 

unsigned int line_number = 1;
ifstream file1("data1.txt");
ifstream file1("data2.txt");
ifstream file1("data3.txt");
ifstream file1("data4.txt");
ifstream file1("data5.txt");
ofstream out("output.txt");

std::string input1;
std::string input2;
std::string input3;
std::string input4;
std::string input5;

getline(file1, input1);
getline(file2, input2);
getline(file3, input3);
getline(file4, input4);
getline(file5, input5);


out << line_number
    << ", " << input1
    << ", " << input2
    << ", " << input3
    << ", " << input4
    << ", " << input5
    << "\n";

The above code is the fundamentals. The reader and OP need to put code into the loop and add error checking. This is structured in "batch" mode where many related operations are clumped together.

Yes, the above code could be simplified, but it is for illustration purposes.
