private void PopulateIt(CheckBoxList chk,string dataTextField, 
             string dataValueField,sqlRawItems) //I don't really know what sqlRawItems is
{
  chk.DataSource = dataTable.dbdata(sqlRawItems, 1);
  chk.DataTextField = dataTextField;
  chk.DataValueField = dataValueField;
  chk.DataBind();
}

Then you can call it wherever you need it.

PopulateIt(CheckBoxList1,"StudentName","StudentID",sqlRawItems);
PopulateIt(CheckBoxList2,"StudentName","StudentID",sqlRawItems);
PopulateIt(CheckBoxList3,"StudentName","StudentID",sqlRawItems);
PopulateIt(CheckBoxList4,"StudentName","StudentID",sqlRawItems);
PopulateIt(CheckBoxList5,"StudentName","StudentID",sqlRawItems);

I'm not sure how ASP.Net works, but in winform you could do somthing like this for looping through your controls

foreach (CheckBox chk in this.Controls.OfType<CheckBoxList>())
{  
   //Of cource assuming that all the controls will bind by same data
   PopulateIt(chk ,"StudentName","StudentID",sqlRawItems);        
}
