Regular octagons have equal sides.
8
Do you mean sides? That's 8. If you mean sizes, as you spelled it, then a given octagon has only one size, but the shape generally referred to as an "octagon" can have an infinite number of sizes.
It has infinitely many sizes.
Yes. A regular octagon must have equal angles, but an irregular octagon cannot have all its angles equal
A regular octagon has eight equal angles. An irregular octagon need not have any equal angles, although it may have some.
an octagon * * * * * An octagon need not have equal sides. For that it would have to be an equilateral octagon (though not necessarily regular).
An octagon is a plan figure with eight sizes, a regular octagon is an octagon with all the eight sizes being equal to each other
An infinite number of sizes. Start off with any octagon. Multiply each of its sides by any number x (>0). That will give a similar octagon that is x times as large. The number of such octagons then is equal to the number of possible values for x, ie infinite.

The answer depends on their sizes! A small square will have a smaller area but a huge square will have a bigger area. Do the two shapes have equal sides, apothems, diagonals? Also, a square is a regular shape, what about the octagon?

It depends on the octagon and how symmetric it is.
A regular octagon has eight equal sides, but in general the sides of an octagon don't have to be equal as long as there are eight of them.
Only if it's a regular octagon.
