! I hate to be that person, but actually you did call them friends: "What will Potter's friends do when they realize that he made them orphans". In fairness, you also called them fellows a few lines later. I'm also not criticizing Draco's choice, if anything I'm surprised at how passive he was compared to the initial Draco who was willing to torture Harry. The other students think their parents were sacrificed by Voldemort in his resurrection ritual; remember that Harry kept his involvement a secret and Obliviated Draco after their talk.

! Hermione's resurrection wasn't a single act, but a series of separate spells.

! First Harry untransfigured her corpse, then healed her to a nonmagical state: "Girl'ss body iss resstored. Ssubstance iss repaired. But not magic, or life... thiss iss body of dead Muggle."

! Then Voldemort was about to shock her to wake her up when Harry had the insight about the True Patronus bestowing magical ability: "Intuition or Tom Riddle’s memory told Harry that the life and magic that had just flowed into Hermione would never return to him, either one. It hadn’t been all his life or all his magic, not by a long shot, there hadn’t been time to expend that much, but whatever he’d just expended was gone forever."

! And proof (ish) that the Patronus worked: “Fascinating in- deed,” Voldemort hissed. “She is alive, and magical, and not another Tom Riddle as I feared you might have made her.”

! So Hermione's already resurrected, and no actual transformation has been done, save for the Transfiguration to restore her body and Harry's Patronus. Voldemort clearly says that Harry didn't copy his soul into her. I suppose you could argue that Harry instead created a new soul, but it seems unlikely that Voldemore wouldn't have mentioned it.

! In fact, Voldemort says souls aren't real much earlier, when he's on his deathbed talking to Harry and Harry offers him the original Horcrux spell:

! “Would be pointlesss sspell from beginning, if ssoulss exissted. Tear piece of ssoul? That iss lie. Missdirection to hide true ssecret. Only one who doess not believe in common liess will reasson further, ssee beneath obsscuration, realisse how to casst sspell. Required murder iss not ssacrificial ritual at all. Ssudden death ssometimes makess ghosst, if magic burssts and imprintss on nearby thing. Horcrux sspell channelss death-bursst through casster, createss your own ghosst insstead of victim'ss, imprintss ghosst in sspecial device. Ssecond victim pickss up horcrux device, device imprintss your memoriess into them. But only memoriess from time horcrux device wass made. You ssee flaw?”

! So I'm pretty sure the whole idea of a soul is a red herring and irrelevant. In any case, Hermione is already fully resurrected to her pre-death state, but Voldemort wanted to make her indestructible so she would serve as a more reliable restraint on Harry. That's why he sacrificed all those creatures: “Sshall ssacrifice my fallback weapon, and girl-child sshall gain troll'ss power of regeneration. Transsfiguration ssicknesss iss nothing before that, if perchance it wass not fixed by previouss ritual. And no knife sshall sslay girl-child, nor cutting cursse, nor ssicknesss take her.”

! Being eaten by a troll isn't heroic, but Hermione pretty clearly expressed a desire to be a hero before that. All the stuff with the bullies, the SPHEW demonstration outside Dumbledore's office, the constant nagging about trusting Quirrel.

! I named her bodyguard because this is what she will do now. First of all because Harry brought her back (well, not Harry actually)

! Harry almost immediately tried to give her the "destroy Azkaban" quest:

! “Are you willing to do that?” Harry said instead. “The quest that I think might be your destiny—and no, I don’t know any specific prophecies, it’s just a guess—involves literal descent-into-Hell type stuff.” ... I’m done with trying to be a heroine,” said Hermione Granger with the eastern sky brightening around her. “I shouldn’t ever have gone along with that entire line of thinking. There are just people who do what they can, whatever they can. And there are also people who don’t even try to do what they can, and yes, those people are doing something wrong. I’m not ever going to try to be a hero again. I’m not going to think in heroic terms if I can help it. But I won’t do any less than I can—or not a lot less, I mean, I’m only human.”

! Despite her rejection of the hero label, she sounds pretty heroic to me. She explicitly names helping people as a goal, which makes it sound like she wouldn't be content being a bodyguard. Plus, Harry is probably going to become a second Voldemort in terms of power before long, further negating the need for a bodyguard.

! secondly, because in case of death or even losing of consciousness, Harry will cause release of the one who reanimated her.

! On death, yeah. That's a major flaw with the sealing plan. But not on blacking out. The time when his marshmallow rock untransfigured during the mock battle was from using all his mana:

! Harry suspected he was going to get a lecture from someone-or-other about not exhausting his magic to the point of unconsciousness over a children’s game. But he hadn’t hurt Mr. Goyle when he’d lost his temper, and that was the important thing. Then Harry’s mind clicked on another implication, and he looked down at the steel ring on his left hand’s pinky finger, and almost swore out loud when he saw that the tiny diamond was missing and there was a marshmallow lying on the ground near where he’d fallen.

! He’d sustained that Transfiguration for seventeen days, and would now need to start over. Could’ve been worse. He could’ve done this fourteen days later, after Professor McGonagall had approved him to Transfigure his father’s rock. That was one very good lesson to learn the easy way. Note to self: Always remove ring from finger before completely exhausting magic.

! You're right that the seal is far from permanent and will require stronger measures. In the meantime, at least if Voldemort gets loose he'll have a blank mind and won't immediately start murdering people.

! Oh, she could try to release him herself and ask to bring her soul back, which is obviously impossible.

! Souls aren't real, and I outlined my reasoning above. But I doubt Hermione would actually do this. There was an entire interlude where Voldemort tried to trick Hermione into bargaining with evil by mindwiping and trying again and again and again... and he failed. Hermione does not make deals with evil.

! Yeah, detection would be a vastly superior option. Unfortunately, I don't think anyone except maybe Voldemort knows how to do that, given that most people don't even know Horcruxes are a thing. He also didn't have a choice -- when Hermione was rezzed, Voldemort still had Harry as a captive, and it wasn't until later that he thought of the transfiguration stuff. It is interesting to note the parallels between their thinking, but I still think Harry did the best he could, given the constraints. A permanent solution can be another project for the Bayesian Conspiracy.
