Answer 1

I just tried a sample i don’t know whether it works for your or not this is just a sample try as per your requirement

lst=new ListItem("123");
if (DropDownList1.Items.Contains(lst))
{
   for (int i = 0; i < DropDownList1.Items.Count; i++)
   {
     if (DropDownList1.Items[i].Equals(lst))
     {
        DropDownList1.Items[i].Attributes.Add("style", "background-color: red;");
    }
  }
}

As per your second requirement

ListItemCollection lstr = new ListItemCollection();
lstr.Add("123");
lstr .Add("1234");
foreach (ListItem lst in lstr)
{
if (DropDownList1.Items.Contains(lst))
{
for (int i = 0; i < DropDownList1.Items.Count; i++)
{
  if (DropDownList1.Items[i].Equals(lst))
  {
    DropDownList1.Items[i].Attributes.Add("style", "background-color: red;");
  }
 }
 }
 }
