The present paper presents some new results on so-called realization problems of graphs as Reeb graphs of Morse functions having nice structures. More precisely, we assign (types of) closed and smooth manifolds of suitable classes to edges and construct good functions whose preimages are as prescribed.The Reeb graph of a smooth function is a graph which is the quotient space of the manifold of the domain obtained by the following equivalence relation; two points in the manifold is equivalent if and only if they are in a same connected component of a same preimage. Note that in considerable cases such as cases where there exists finitely many singular values.Reeb graphs represent the manifolds of the domains compactly in general. They are not only fundamental and important tools in geometry using differentiable functions and maps as fundamental tools, but also in applied mathematics or applications of mathematics such as visualizations. Realization problems have been also fundamental and important.
