Tox Ids are, by the most part, public keys of a public key encryption 
keypair.
So no, you can't impersonate someone by just knowing their Tox Id.

Depends on how clients are implemented, i.e. if they share the same tox 
profile.

Running more than one client with the same Tox Id at the same time is 
not supported.
You can do it, but what happens is an undefined behaviour.

I have no idea what you are saying.
If you want you client to ignore all friend requests but from certain 
Tox Id, then code your client to do just that.

Messages are sent encrypted. Toxcore handles encryption and decryption 
seamlessly for you.

Clients send messages encoded as UTF-8, so make sure you use UTF-8 
encoding for your messages.
Also, make sure the messages you send don't exceed the maximum length.
