No it can't
No, it is not possible.
yes
Assuming that the question refers to a regular octagon (not a regualr otagon), the answer is no.
A regular pentagon is one example.
Start with one octagon.Place an octagon along every other side of the first octagon. This creates square gaps which can be filled using the squares. At this stage the general pattern should be evident.
An octagon can be used to create a tessellation, but an octagon cannot tessellate on its own.
No, it is not possible.
false, there would be gaps.
square
yes
Triangle :)

No Internat angle of a regular octagon is 135°. No multiple of 135° will make 360°. Thus at any point there can be at most two octagons and a 90° gap. Ratty
Yes, any quadrilateral can be used.
An octagon cannot tessellate because when you put about 4 together, there are gaps in between the shapes, which is not allowed in a tessellation. When you put together 5 octagon's, some of them are overlapping and there still are gaps. Therefore, an octagon cant tessellate.
true
Yes, they will.
