Solution 1

use Validation Groups
Specifying Validation Groups[^]
set same validation group for button1 and requiredfieldvalidator1 and another validation group for button2 and requiredfieldvalidator2

use ValidationGroup Property

    <asp:requiredfieldvalidator id="Req9" runat="server"  ValidationGroup="a"
                    ErrorMessage="Enter PINno"></asp:requiredfieldvalidator>  
 
     <asp:requiredfieldvalidator id="Req10" runat="server" controltovalidate="TextBox2" ValidationGroup="b"
                    ErrorMessage="Enter PINno"></asp:requiredfieldvalidator> 
 
<asp:button id="btnsubmit" runat="server" ValidationGroup="a" 
                     Text="Button1" onclick="btnsubmit_Click1"/>  
 
<asp:button id="btnsubmit1" runat="server" ValidationGroup="b" 
                     Text="Button2" onclick="btnsubmit1_Click1" />

Group the Textbox1 with Button1 and Textbox2 with Button2
