What about 4 sided figures? We know squares, rectangles, parallelograms and rhomboids are OK but are there any others?

Well, kites are well known to tessellate. In fact, any 4 sided shape will tessellate if put back to back with a copy of itself - it forms a hexagon with opposite sides equal. As we have seen, these will always tessellate.
