Halo: Reach is the story of the Spartan IIs that tried to defend the orbital MAC guns generators from the covenant ground forces while the Chief along with two other Spartan IIs (I think) were in charge of purging a badly damaged UNSC ship of all data relating to the location of Earth and any other planets held my humanity and the UNSC.
Halo: The Flood is the retelling of the Halo:CE game with a few side stories.
Halo: First Strike fills the gap of time between Halo:CE and Halo 2, explaining what happened after the Master Chief destroyed the Halo ring and how he managed to get back to Earth, also explaing how Johnson made it back as well, despite not being explained in Halo:CE. (NOTE) Halo: First Strike is, also in my opinion, one the the best of all the Halo novels.
Halo: Ghosts of Onyx is a story told in parallel to Halo:CE, Halo 2 and Halo 3, (SPOILERS AHEAD) showing what happened to Halsey after her encounter with Chief and Kelly (Again I think) during Halo: First strike.
Halo: Contact Harvest is a prequel to all the prior books, giving a glimpse of how the covenant-human war began. Also, it is the ONLY Halo novel written by a Bungie employee (Joseph Staten) who also wrote the storyline for Halo 3 and Halo 3: ODST.
Halo: Cole Protocol is a book detailing the story of captain Keys from Halo:CE
Halo: Cryptum and Halo: Primordium (and the Silentium which is to be released in Jan. 2013) all take place 100,000 years BEFORE any of the Halo storylines, book or game.
Halo: Glasslands and Halo: The Thursday war are both books that take place between Halo 3 and Halo 4.
So yes, they all fit canon, and it is that way on purpose, Halo franchise director and former Bungie community badass FrankO' conner has said that it is important to not have any contradictions in the Halo universe and that all media released be it a game or a book will tie in to each other.
