are this

and this

the same shape (cubinder I believe) from different angles or rotation?

or is the second one made of 4 cubinders connected like lines to a square?



another question that i think i already know the answer to but just to make sure...
a line segment is to a circle what a cylinder is to a duocylinder? you get a sphere from a polygon with infinite sides/line-segments. you get a douprism from a prismic sides/cylinder with infinent cylinders.

Yes, they are both the cubinder. Cubinder is square x circle, and contains four cylinders as cells. You can see the squares and the circles, and the four cylinders in both pictures.

You're not being very precise here. A duocylinder is a rotated cylinder, but a circle is a rotated point. A polygon with infinite sides is a circle. I'm not sure about the duoprism statement. I know that the duocylinder can be expressed as the limit of duoprisms, but I can't remember how that works exactly.
