Very important to point something out.

There is no difference between the Aedra and Daedra. They are essentially the same type of creature. A spirit. The Aedra are simply identified as Aedra ("our ancestors" by Elves), because they were the benevolent spirits that formed Mundus (via by Magnus and Lorkhan's planning and/or trickery). The Daedra are simply pretty much every other spirit that did NOT help with the creation of Mundus. Specifically, the spirits that did not create Mundus, and also did NOT return to Aetherius with Magnus.

That said, the Daedric Princes are theoretically, killable.

Instead of working unanimously to create a plane as the Aedra did; the Daedric Princes sought to create their own individual planes within Oblivion without sacrificing their ability to self-actuate. (I guess it can be argued that the DP aren't satisfied with their realms considering their obsession with Nirn.)

It stands to reason, that not all of the Aedra are incapable of taking form (e.g. Akatosh manifesting himself through' Dragonborn Martin Septim once the Amulet of Kings was shattered.), or interacting with Nirn (Stendarr creating a barrier that Mannimarco and Molag Bal could not penetrate). So exceptions to the rules do exist.

Then you have the unknown power of the millions of Magna Ge living in Aetherius, outside of Oblivion (possibly serving as caretakers for the souls of mortals that pass away from Nirn).

To my understanding of the lore, I've concluded that most of the Daedric Princes can be destroyed or perma-banished by:

1. Akatosh - As the God of Time, and the First God, all other life in all existence only exists in a consistent form because of him. It is said that he IS time, and time IS because of him. It's no wonder he is the most worshipped and is considered the most powerful. He clearly DOES pay attention to things that are happening in Nirn and Oblivion as a whole, and it seems he is capable of interfering in matters absolutely anywhere in Nirn and Oblivion, as he sees fit (e.g. his rescuing of the Soulless One and The Prophet from Coldharbour). Akatosh's power is great enough to prevent all Daedra from entering Nirn, unwanted. Although, it does not prevent Daedra from inviting mortals to leave Nirn. It's not clear whether this is an intentional allowance on Akatosh's part, is a part of some "compact" (as referenced by "Haskill"), or is a clear limitation on Akatosh's power. Mannimarco was going to use Akatosh's Amulet of Kings to steal the power of Molag Bal, and make himself a Daedric Prince. CONJECTURE: If the Amulet of Kings, being merely an amulet with some of Akatosh's blood, is capable of making of breaking a Daedric Prince (both within and without the DP's realm), then I would conclude that a concerted effort on Akatosh's part to destroy a DP is plenty possible. As for Akatosh himself being destroyed; Akatosh's death means everyone's death. To kill Akatosh would require a being that exists outside of time. The only "being" therefore, that I know of lore-wise, that would survive a "Dragon Break" sufficient enough to destroy Akatosh, would be "Sithis". Whether or not Sithis is capable of causing such an event is a different topic.

2. Mehrune's Razor - But this is only theoretical. The weapon was forged by Mehrune's Dagon for mortals to banish Daedra with. To prevent Daedra from using it on each other, it has a feature that would permanently banish them to the "Voidstreams of Oblivion". Whether or not this "safety feature" would work if another Daedric Prince attempted to use the Razor is purely speculation; as is the likelihood that a Daedric Prince would be fool enough to use the Razor, if it did have such power.

3. Magnus and the Magna Ge - They are the denizens of Aetherius, the place to which mortal souls go when freed from Nirn. It is speculated that the "Daedric Prince" Meridia, is one of the Magna Ge, and that she was banished from Aetherius for her association with "illicit spectra". Not sure what this means. It could mean her association with Daedric Princes; whom I would imagine Magnus and the Magna Ge want no association with (due to their malevolent spheres?). Meridia as a Magna Ge, is considered a Daedric Prince, but she was cast out of Aetherius by the Magna Ge. If they can overpower her, and her power is on par with a DP, then I would imagine that a concerted effort by ALL of Aetherius would be devastating to a DP's health, if it's not killed.
