First off, it isn't YOU your pup is guarding, you're just another resource. This is not good behavior at all. A horrendous fight can break out over ANY resource guarding and that includes you.
I hope someone else on here can answer this. I'm not very good with it, but for starters I'd give them each time with you out of a crate, while the others are crated. They have to stop the guarding.
