OK, rewatching the game up through 5-0....
1-0: Lots of blame to go around here. Luiz is the primary culprit, but Marcelo deserves plenty of blame here as well, as does Scolari. Marcelo's caught far too up field after taking a pass from Hulk, and is dispossessed by a combination of Khedira and Schweinsteiger, who rampage down the right side. Marcelo's able to recover and force the corner, but it could've been worse right there.
On the corner, Luiz is marking Mueller, Fernandinho is marking Klose near the goal. Klose drifts in behind Luiz, who isn't sticking closely enough to Mueller, and effectively sets a pick. By the time Luiz reacts, he cant fight past Klose (Fernandinho gets in his way too, they literally run into each other) and by then it is too late.
Cesar can't do much with it, but Marcelo is inexplicably standing inside the goal line. Seems like he could have been deployed much more effectively by Scolari on situations like this.
3 demerits: Luiz

2-0: Right before this goal, Marcelo is again caught too far upfield (22'), and Khedira starts the break through Mueller down the right side, leading to a deep throw-in.
Upon the throw in, Mueller plays a pretty simple pass to Kroos, which Fernandinho gambles on trying to intercept, and doesn't get to in time. At this point Kroos has control, is 25 yards out, and has Fernandinho on his back and the Brazil back four has no cover. He comes forward and Dante comes out to challenge him. Kroos plays a lovely ball through Dante to Mueller, who has cut in from the right, and at the same time, Klose has darted from the 18' towards the middle of the box. Mueller controls and taps to Klose, who is merely being watched by Luiz at this point (he never even tries to hustle) and pursued by an out-of-position Maicon, who can't do much but watch. Cesar might have done a bit better here, but again most of the fault lies on the shoulders of Luiz again.

3-0: Far too easy to penetrate again down the right side. Khedira has room in front of him up until about 25 yards, where Hulk is in front of him. Gustavo is playing way too far off him at this point, jogging in his general vicinity and giving him plenty of time to make a pass. Hulk stops tracking Lahm so he can step up to Khedira, and Marcelo is poorly positioned and too slow slow to recognize and close out on Lahm. He's nowhere near the one time pass that Lahm plays back through the box. Fernandinho is again out of position to stop Mueller who it comes to initially, but he scuffs at it. Maicon is sucked in all the way to the middle of the box, Luiz is standing hopelessly at the six, nowhere near Klose, and Bernard is slowly jogging towards the action, presumably. Kroos takes it one time and beats Cesar with a saveable shot.

4-0: This one is all Fernandinho. Dante plays him a simple pass with his back to the Germans, which he handles casually, and Kroos catches him from behind, steals the ball cleanly, and is off to the races. Dante does his best, but a simple 1-2 with Khedira leaves both he and Cesar woefully out of position, leading to a simple finish for Kroos.
It should be noted that as this breakdown is happening, Luiz is slowly jogging to the action and is out of position the whole time, far off to the right. Watch a replay, it is seriously galling.

5-0: Luiz chips another pass forward to Germany's backline, presumably towards Hulk but its badly played. Hummels chests it down, and easily skips past Fernandinho. Inexplicably, Luiz comes all the way out to challenge him and he and Gustavo almost collide into each other, but not before Hummels slips a pass to Khedira, who breaks in with Maicon and Marcelo trailing out of position, and only poor Dante left to try and stop him. Dante challenges him effectively, but Khedira lays off a pass to Ozil on the left. Dante turns to him, and the ball is back to Khedira, alone, who puts it home. It should also be noted that Marcelo completely lost track of Mueller during this break, but he wasn't even needed.

I'm assigning an additional 3 demerits to Scolari for picking such a defensive XI that lacked playmakers/ballhandlers that could've provided relief from Brazil's pressure, and two additional demerits to Cesar for not martialing his back line better. But make no mistake, this doesn't fall on Fred or Scolari, Brazil was undone by Luiz and Fernandinho primarily, with plenty of help from Marcelo. Perhaps Silva would've been able to wake them up after the first couple, but Dante wasn't Brazil's primary issue, nor was Maicon.
To provide some perspective, Fernandinho was widely considered to be the best defensive midfielder in the best domestic league this year, Manchester City won the EPL and he was rightly credited for helping their defense stay so steady. Opinions are more split on Luiz, who wasn't a first-choice CB for Mourinho at Chelsea and was sold to Paris St. Germain for the highest transfer fee ever for a defender. He takes pk's, he's capable of scoring on free kicks, and he advances forward from the CB position, which few CB's ever do. But he also isn't considered great in terms of his positioning/defensive acumen.
Marcelo is the starting LB for Real Madrid, who won the UEFA Champions League this year, and is also considered one of the best LB's in the world.
Final total:
13 demerits: Luiz
13 demerits: Fernandinho
7 demerits: Marcelo
5 demerits: Cesar
