Answer 1

I am not expert of loopback but try this code:
var Registration = app.models.Registration;
console.log(Registration);
app.model(Registration);

Answer 2

User is the model name.
var user = app.models.User;
resetPassword is function name of the user model, which
take two parameter new_pwd and token,
user.resetPassword({
new_pwd: new_password,
token
}, (err, data) => {
if (err || !data.status) {
return err || data;
} else {
return data;
}
});
