A square has vertices which form 90 degree angles. Four of these can meet at a point and cover 360 degrees. This ensures than there are no wedge shaped gaps or overlaps at the points where the tessera meet. Also, the side lengths are all the same, so there are no gaps or overlaps along the side lengths.
Yes a square will tessellate on its own
No, but an octagon and a square can tessellate.
No, a square and a pentagon cannot tessellate together. In order for two shapes to tessellate, their angles must add up to a multiple of 360 degrees. A square has angles of 90 degrees, while a regular pentagon has angles of 108 degrees. Since 90 and 108 do not add up to a multiple of 360, these shapes cannot tessellate together.

A square will tessellate leaving no gaps or overlaps but a circle does not tessellate.
