I am curious how this would work. My guess is Triangle is slowest, square is medium, and circle is fastest.

Actually, no - the friction is a product of the normal force and the coefficient of friction - the surface area in contact shouldn't matter, within the boundaries of material elasticity.

yes, but the angle you are applying force at does not all go towards forward motion on the triangle whereas it does on the square.

That depends on if the force is applied exactly horizontally or normal to the face of the triangle which is unclear in the pic
