             {
                 Response.Write(peopl.OtherName + "<br />");
             }
 
        }

Something like this maybe?

var lst = new List<string>();

for (int i = 0; i < 5/*Number of columns*/; i++)
lst.Add(rd1["Param" + (i + 1).ToString()]);

why does the value you look up change ? this whole setup looks odd to me, and like a hard to maintain hack. I think you need to explain why your data is in this format.

You can use it

List<Dictionary<string, object>> people = new List<Dictionary<string, object>>()
             {
                 new Dictionary<string,object>() {},
                 new Dictionary<string,object>() {}
             };

            people[0].Add("FirstName","abc");
            people[0].Add("Age", 15);

            people[1].Add("FirstName","xyz");
            people[1].Add("Age", 25);

            var peopleDataNew = from pep in people
                                where Convert.ToInt32(pep.["Age"]) > 20
                                select pep;
