First, you are not passing the parameter values in the query strings correctly.

Response.Redirect("ContactInformation.aspx?FirstName=&LastName=&DateofBirth=" + txtFirstName.Text +txtLastName.Text + txtcalender.SelectedDate);
Response.Redirect("DisplayPage.aspx?EmailId=&MobileNo=" +  txtEmailid.Text + txtMno.Text);

You need to put the parameter values after the = sign for each parameter:

Response.Redirect("DisplayPage.aspx?EmailId=" +  txtEmailid.Text + "&MobileNo=" +  txtMno.Text);

You need to fix the first one similarly.

Second problem:

You are not passing the values from the first page to the third page at all.  You need to add the values you captured from the first page to the query string going to the third page.

Response.Redirect("DisplayPage.aspx?EmailId=" +  txtEmailid.Text + "&MobileNo=" +  txtMno.Text + "&FirstName" + FirstName + "&LastName" + LastName + "&DateofBirth" + DateofBirth);

I answered your first question.  Please mark it as the answer.

Your second question should be a separate post, is is not related to your first question.

And when you ask it in a new post, please be a lot more clear about what you are asking.  I don't understand that question.
