Integral Separation of disjoint submanifolds of $\mathbb{R}^n$

Assume that $M_1, M_2, \ldots , M_k$ are $k$ disjoint compact submanifolds of $\mathbb{R}^n$ of the same dimension $m$. Assume that $\lambda_{ij}, \; 1\leq i,j\leq k$ are $k^2$ arbitrary real numbers.

Are there $k$ differential $m$- forms $\alpha_1, \alpha_2,\ldots, \alpha_k$ with $\int_{M_{i}} \alpha_{j}= \lambda{ij}$?

The motivation for this post is that a positive answer to the above question implies that the number of closed orbits of a planar vector field $X$ is less than the codimension of the range of the following linear operator:

$$L_X:\Omega^1(\mathbb{R}^2)\to \Omega^1(\mathbb{R}^2) $$
