It's the Kamijou Faction, not the Touma faction. Anyway, to answer your questions:

Some (like the Return of the Winged One) do see the faction as a threat, but it would be fairly difficult for the faction to be destroyed. Not only does it consist of many members, some of whom are incredibly powerful on their own, but I don't think anyone in-universe even knows the full list of members.

Only some of the faction's members are loyal to Touma, the ones like Accelerator, Mikoto etc. The rest, like Mugino or Acqua, only work with Touma if their interests align.
