I know OpenDNS and DNSCrypt, but I haven't used the other products.
However, I don't see how they are related to your Tor use?
When you use the Tor Browser Bundle, all your DNS requests will be done over Tor, the Tor exit will do the DNS resolution for you. You really shouldn't mess with that.
If you use any of these products, they *should* (have only experience with OpenDNS) not touch your Tor DNS, unless they are doing some really fancy stuff. You can use such products, if you really must, they *should* only tamper with your non-Tor connections.

No, I've never heard any of these, but wait if others disagree with me. Tor and non-Tor traffic traffic, at the same time, is expected. People have their automatic updaters, instant messengers or even Firefox running next to the Tor Browser Bundle.
Of course, you can get more security by isolating machines. One machine/internet connection exclusively for Tor use and one exclusively for non-Tor use offers some advantages, but that's not expected.

I don't see why it were easily. Did you read ?

Being a relay, doesn't prove, you are a Tor user. For example there are Tor servers in the amazon cloud and it's unlikely, the the owner uses the same server as a client.
Please read .
Tor does not hide the fact, that you are a Tor user. You can do this to some extend, if you are using bridges, or better private bridges, or even better private obfuscated bridges.
Tor concept for providing anonymity is different, in the set of all Tor users, you look equal. If you were the only user, you were indeed not anonymous, but that's not the case. Perhaps  is useful as well.
I read, dunno if it's still valid, I don't find the link, being an relay (or was it an exit?), can also enhance your anonymity, since there is no prove, that it was you, who caused the traffic. There are also some drawback, see .
If you scare being a public relay for that reason, please consider hosting a private obfuscated bridge. It's published nowhere, is needed and you decide, whom you give access.

No. They make promises, which they can not held. Research them, you will find negative things. Their encryption is bogus, since the server has the ability to break it. Rather use GPG, which is well designed, since not even the authors can break the encryption.

Thanks for hosting a relay or bridge.
