Change to the following:

 for (int i = 2; i < SCdataGridView1.Rows.Count;i++)
            {
                int malecount = 0;
                if (SCdataGridView1.Rows[i].Cells[8].Value.ToString() == "Male") //here the error occure because I put here i 
                {
                    malecount = malecount + 1;
                    SClabel6.Text = malecount.ToString();
                }
            }

Error is Because of you have Written Because Index of DataGridView is Always 1 Less then its Row Count

for (int i = 2; i <= SCdataGridView1.Rows.Count-1;i++)
            {
            int malecount = 0;
           if (SCdataGridView1.Rows[i].Cells[8].Value.ToString() == "Male")
                {
                    malecount = malecount + 1;
                    SClabel6.Text = malecount.ToString();
                }
            }
