A regular octagon has #0# right angles—all its vertices are #135˚#.

The angle measurement can be found through the formula #(180˚(n-2))/n#, where #n# is the number of sides in a regular #n#-gon.

This isn't to say octagons can't have right angles.

The following picture is of an irregular octagon with #2# right angles.
