Here it is: On the top center. If it's two, they just go on either side. Third goes behind. I imagine four would double up on both sides, and, well, they show what five looks like. So it's pretty clear. Of note: The Silencer can only be escorted by two or three TIE fighters, not a full five. Of course, I don't know why one would want to pay for that many (to keep SR Kylo alive I guess?) but it'll look just like Kylo and his wingmen in TLJ, which is pretty... well, epic. Incidental
