That's hard to imagine and even if it were true, it would be hard to measure. With a proxy (not a CDN) it would be more possible, but CF is a CDN. Therefore, you save a huge amount of time resolving the IP address and this benefit is far greater!
There is no special way or method. Varnish is a page cache for HTML output and Redis is a MySQL cache, so there is no need for special adjustment to work each cache, but Redis is obsolete if a page is already cached. You can use Redis indepentently if any other page cache used.
You can use LiteMage and Redis, but LiteMage and Varnish will cause conflicts.
Two page caches don't double the page cache benefits. Use LiteCache instead and double the speed of LiteSpeed:
