1. Marguerit is most certainly dead. She went down deep, deep enough that Paul couldn't see her and he went deeper down also. Even if she didn't get killed trying to kill whatever attacked the base, she would have probably drowned. There is no brain coral anywhere near the Deep Grand Reef, and there is no place to get oxygen. There is no evidence they connected pipelines down to the deep. Plus, she probably sunk all the way down to the Lost River, where a Crabsquid or River Prowler could have killed her, or she could have just sunk into the brine which would have poisoned her. Any way you slice it, she probably died.

2. Medical Officer Danby died because he wasn't in contact with the unstable Enzyme 42. It's likely that he swam out into the water and got infected from that. He also could have come into close proximity with an infected animal, which may have sped up the infection process. He jumped back into the lifepod for some reason (probably because he was scared of the ampeels) and holed up there, which meant he wouldn't have been in contact with the unstable Enzyme 42 that the peepers bring. Therefore, he died, and an ampeel or something else broke into his lifepod and ate him.

3. Ryley survives the Kharra because he was in constant contact with unstable Enzyme 42. Although there are no alien vents in the biome, there are lots of peepers that possibly migrated there. Ryley is in constant contact with the water (because he didn't run into his lifepod like a wimp), meaning that while he was in constant contact with the Kharra, he was also in constant contact with the Enzyme 42, which delayed Kharra from killing him.

4. Kharra doesn't have to come from 4546b. A data download from the precursors tells us that it was "First encountered during routine network expansion on outer worlds.", thus meaning that Kharra isn't a disease only contained within 4546b. Kharra could have spread from other planets.

5. Why Marguerit? It's never confirmed that Paul was killed either. Is probably that he was killed, but not confirmed. Marguerit is on the same level of possible death as Paul, so why is Marguerit special?

While your theory looks good on the surface, a bit of probing reveals that it is most definitely false.
