As it happens with most software tools, having more than what you need is not better. Conflicts are guaranteed to happen and sometimes nasty ones.
I totally agree with all the replies above and would also recommend to keep CCleaner and Auslogics DiskDefrag. As for the registry, if anything, the benefits you're pursuing by using a registry cleaner will be found in CCleaner as well, so don't worry about getting anything else (dc3 is right, 'highly overrated and can be dangerous' to use these registry cleaners).
There's another little tool that I would definitely advise you to have along-side with whatever security suite you may have, which is Malwarebytes. You may be thinking that I'm contradicting myself, but the fact of the matter is that Malwarebytes is, if anything, a complementary tool not a replacement; and it is quite powerful, succeeding where renowned Security Suites fail.
These three tools are on my every computer, they're an absolute must, that's why I thought I'd give my insight on this as well.
