Backlash is the difference between the tooth space and the tooth thickness, as measured on the pitch circle.
Face width is the width of the gear tooth measured parallel to its axis.
Working depth is radial distance from the addendum circle to the clearance circle. It is equal to the sum of the addendum of the two meshing gears.
Clearance is the radial distance from the top of the tooth of one gear to the bottom of the tooth of other gear, in a meshing gear.
