No, you cannot.
By themselves, only 3: triangle, square and hexagon. But there are combinations: eg octagon + square.
No
Yes. Can it tesselate R^3? Only if its base pentagon is non-regular.
An 8 sided octagon can be either regular or irregular in shape.
No, you cannot.

You cannot use a regular octagon on it's own to make a tiling pattern without any gaps. However a regular Octagon and a square can be used together to make a tessellation. Many people think that regular octagons tesselate on their own because they do not appreciate the need for no gaps.
No.
No, it cannot.
Yes, a regular hexagon does tessellate.

Triangle, square, hexagon.
A regular octagon has 8 sides.
Yes a rectangle will tessellate with no gaps or overlaps
