Please check geometry in SpaceClaim.
Select geometry in structure tree --> Use right click --> Select Check Geometry. (Or Tools - Fault Detection in DM)
The geometry should be error free to proceed.If geometry has any errors, please modify/recreate geometry at those places.
Once geometry is OK, please do share topology. You can find share topology information at following link:
Share topology in important operation before going to Fluent Meshing. If it is failing at some places, it may give errors in Fluent Meshing about surface intersection.
Now if share topology is successful and still you are getting errors in Fluent Meshing, then it could be due to insufficient sizing. Please make sure that you have applied correct sizing to capture different parts. You can find more information about sizing at following link.

Fluent Meshing Watertight Workflow:
This video provides a walk-through of the Watertight Geometry Guided Meshing Workflow for Fluent. The workflow provides a way to import a watertight or \"clean\" CAD geometry, add optional local sizing, create a surface mesh, create fluid/solid regions, and generate a complete volume mesh in a step-by-step interface.
