From looking at your voltages the individual cells are:
1) 3.71v
2) 3.7v
3) 3.73v
4) 3.71v
5) 3.72v
Your readings are not individual cell readings, except the first one. 7.41v readings is of 2 cells, 11.14 is of 3 cells etc.
Did you measure that with a volt/multimeter or charger? From the readings you gave the pack looks fine to me. You can figure out the cell voltages by subtracting the previous reading eg. Reading 1 (cell 1) is 3.71v. Reading 2 is cell 1 and 2 combined, so 7.41v minus cell 1 voltage of 3.71v = cell 2 voltage of 3.7v. etc
If you did measure it with a multimeter, then reading 1 must have been from wire 1 and 2 on the plug. Reading 2 from wire 1 and 3, so measure from wire 2 and 3 to see cell 2 by itself. 3 and 4 for cell 3 etc.
If your readings are from the charger then I don't know what that means, but I don't think it has anything to do with the cells themselves.
