AU: the answer is Dee/Dum.

#6

I follow orders

Given to me directly from the source

I'm the guard dog of this company

And I'm very loyal

I like Red she's my friend

We really get along

Sometimes we hang out all day long

So can you guess who I am?

I hope you can

The next one should be the last

Of our little challenge

AU: So one more left. Good luck.
