A duodecagon has twelve sides and twelve corners. A duodecagon is usually called a dodecagon.
A duodecagon has 12 sides and 12 angles. Like a Dodecagon.

Not sure about a duodecagon, but a regular dodecagon has 12 axes of symmetry.

Yes there is an infinite list of shapes with more sides than an octagon. For example the is a nonagon with nine sides or a decagon with ten sides a duodecagon with twelve sides etc.
Providing that it is a regular duodecagon each exterior angle measures 30 degrees
Duodecagon <--wrong... a duodecagon is a 12-sided polygon. icosagon is a 20 sided polygon.
3 sides: triangle 4 sides: quadrilateral 5 sides:pentagon 6 sides:hexagon 7 sides: heptagom 8 sides: octagon 9 sides: nonagon 10 sides: decagon 11 sides: unodecagon ? 12 sides: duodecagon 13 sides: trisca-decagon? 14 sides: ( I am tired on making up names- try quator-decagon, or look it up.)
