I'm looking for more information about 2 actors and 1 actress who appeared in this show. Can anyone help? Every tiny information would be much appreciated!

This contains spoilers!

1.) The first actor is credited only with the name Lobo in the opening credits of the last 3 episodes (original Spanish airing). He plays Darko Dragic, Oslo's brother, and he's one of the 4 serbs who were digging the tunnel before the heist began and who free's Tokyo from the police van. Take a look at the following YouTube clip:

The actor in the middle at 1:46 min is Lobo. My problem: I can't find anything about him! I searched for him via Google, but nothing comes up. He's probably originally from Eastern Europe (Yugoslavia, most likely) and maybe not a professional actor but an athlete of some sorts (boxing, martial arts etc.).

2.) The second actor I'm looking for is the person who plays Francisco Torres, the older man who works at the Factory and who helps Nairobi to print the new money. Unfortunately, the actor is not credited once - but I would like to find out who this actor is. You can see him in the following YouTube clip at 2:34 min:

3.) The actress I'm looking for is the person who plays one of the young hostages, Silvia Moreno. Berlin isolated her from the other young hostages in episodes 5 and 6 (original Spanish airing) and had some weird interactions with her. I know nothing about this actress - she's not credited at all. You can see her in the following YouTube clip right from the start:

As I wrote at the beginning of the post: Any help to find out the identity of these 2 actors and this actress would be much appreciated!
