How to find Cyrus Pinkney's hidden emblems in the game??? (Batman: Arkham Origins)

Hello. Here I decided to collect all the same hidden emblems of a certain Cyrus Pinkney. I didn’t find many of these emblems, one near the courtroom, another near the old metro station, another third on the pioneer bridge, and that’s all, I can’t find the rest.

In this regard, I decided to turn to you, maybe there are experts who will tell you how to look for these emblems ??, otherwise I was already tired of running around the city in search of these emblems.
