As the top view has 90° symmetry, a 90° side view...
...can look exactly the same as the front view.
A 45° side view can be more interesting, ...
...showing an almost-elliptical profile, √2 times as wide, and one of four edges that go halfway down, to the equator. Initial diagram:
Improved diagram   (construction from cylinders is described later):
The bottom view, for those interested, ...
...is a square, the same as the top view but without the diagonal lines because the bottom half is rounded.
This can be constructed by...
...beginning with this intersection of cylinders:
That produces the following shape, whose edges below the equator are then rounded off, to remove those lines, without affecting the orthogonal profiles or top view.
Sides could be either of two, or maybe even an infinite amount inbetween , depending where you put the point in the middle. These two models are kinda low poly. So you have to imaginethe curvature a bit Here is a link to watch the second one online: a360autodesk
- picture middle point to the top
- picture middle point to the bottom
A possible figure would be the following:
View the design here. (But you won't be able to see the lines for some reason)
I made a quick 3D model on tinkercad which can be viewed here
It seems it is a cylinder, with a couple of rings going round it which form a cross on top. Here is the suspected side view:
I know that there aren't any lines which aren't visible from the top or front, but I'd argue that the rings are a single line, as a circle has a single side, so that these lines are in fact visible from the top.
Apart from that the top view is a square with a cross (imagine the black rings were flat):
And the front view is a circle:
