This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
Perhaps an example of what you are trying to generate would help - along with the relevant code fragments to show us what you have tried so far?

Example:
foreach(list lc in secondlist)
{
create new list and add the record the value to it

}
so we have to value in secondlist,
so we have to find the matching record from Firstlist and insert into new list,
so we will get two new list because we have to different first column name(NAWA01
NAWA03)

When you asking any question please try to give sufficient info to users for getting better response. Because we don't know what is your exact requirement.

What is the value you need as output. Provide details.

I think what you want to do is:

List<string> FirstList = new List<string>();  // contains the 4 records
List<string> Ids = new List<string>();        // contains IDs of interest
List<string> ThirdList = new List<string>();  // list to receive the records of interest

foreach (string id in Ids) {
    foreach (string rec in FirstList) {
        if (rec.StartsWith (id)) {
            ThirdList.Add (rec);
        }
    }
}
