Answer 1

In your grid view you can add these line which will set your page with a group of 5 items
<PagerSettings PageButtonCount="5"></PagerSettings>

Answer 2

Try this for pagination in Grid View.
protected void TeacherGrid_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
myGrid.PageIndex = e.NewPageIndex;
bindDataToGrid();
}
// add columns per your requirement and bind the grid with data source.
<asp:gridview id="myGrid" runat="server" AutoGenerateColumns="False"
AllowPaging="True" PageSize="5" OnPageIndexChanging="myGrid_PageIndexChanging">
<Columns>
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:Label ID="lbName" runat="server" Text='<%# Eval("Name")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:gridview>

Answer 3

In your GridView you have to give the size that you want to show the number of results in the GridView also in code behind you have to set your page index so whenever you go to the next 5 records, it will show the next 5 records instead of same.
Fix the PageSize also use a OnPageIndexChanged to show the unique records every time.
<asp:GridView ID="myGridView" PageSize="5" OnPageIndexChanging="myGridView_OnPageIndexChanging" >
in codebehind you write this code in you OnPageIndexChanging...
protected void myGridView_OnPageIndexChanging(object sender, GridViewPageEventArgs e)
{
this.myGridView.PageIndex = e.NewPageIndex;
this.myGridView.DataSource = this.Session["myData"];
this.myGridView.DataBind();
}
