  We demonstrate the existence of branched immersed 2-spheres with prescribed
mean curvature, with controlled Morse index and with arbitrary codimensions in
closed Riemannian manifold $N$ admitting finite fundamental group, where
$\pi_k(N) \neq 0$ and $k \geq 2$, for certain generic choice of prescribed mean
curvature vector. Moreover, we enhance this existence result to encompass all
possible choices of prescribed mean curvatures under certain Ricci curvature
condition on $N$ when $\dim{N} = 3$. When $\dim{N} \geq 4$, we establish a
Morse index lower bound while $N$ satisfies some isotropic curvature condition.
As a consequence, we can leverage latter strengthened result to construct
2-spheres with parallel mean curvature when $N$ has positive isotropic
curvature and $\dim{N} \geq 4$. At last, we partially resolve the homotopy
problem concerning the existence of a representative surface with prescribed
mean curvature type vector field in some given homotopy classes.
