Not for contiguous spaces. Think of a triangle surrounded by three rectangles. There's no way for all three outer rectangles to touch without enveloping the center triangle. There are only two directions you can go, and as long as the center triangle is enveloped, it cannot connect to a fifth shape without separating two of the outer shapes.
Alright, non Euclidean maps it is then!
