Hi @mail4mithu,
I understand that you have a question regarding custom Login pages based on Applications.
Yes, it is possible to render a different Universal Login Page based on the application. To do so, I recommend modifying your Universal Login Page to conditionally render the Universal Login Page based on the clientId.
Here is a small snippet to get you started.
if(config.clientID === "{CLIENT_ID_GOES_HERE}") {
var lock = new Auth0Lock(...)
}
else
var lock = new Auth0Lock(...)
}

Please let me know if you have any questions. I would be happy to clarify.
