How can I do load Balancing in varnish ?
I have two backends with different hardware configurations. Can I do load balancing in the ration of hardware, like out of 4 only 1 request should go to 2nd backend

Try the following VCL config. This is for Vanish 4 and I haven't tested this yet, so make a backup of your existing VCL file.
import directors;
backend web1 {
.host = "1.1.1.1";
.port = "80";
}
backend web2 {
.host = "2.2.2.2";
.port = "80";
}
sub vcl_init {
new apache = directors.random();
apache.add_backend(web1, 3);
apache.add_backend(web2, 1);
}
