Subset of the integers with certain properties
I'd consider first two related questions: what is the largest $n$ for which there exists an $n$set $S \subseteq \{1\ 2\ \ldots\}$ such that for every $A\subseteq S$ the sum $\sum_{a\in A}\ a^2$ is a square or a third power; and for the other question replace $a^2$ by $a^3$, and otherwise the question would look the same. Indeed, when a set of squares and cubes is large than the set of its squares or its cubes is at least half that large.

Magic squares with specific properties
@Daishisan, because Noam's 5dim affine space is actually 4dimensional. And the rest indeed follows.

Extremely messy proofs
There is a nicer tool than nets and filters, and it is purely topological.

Finding a suitable number
Except that I missed the condition $\ q\ge 17$.

Finding a suitable number
@barak, your set of primes may be empty; actually, it always is empty unless $\ m=r_n.\ $ For instance, Tina's $\ q\ $ for $\ (m\ n)\ =\ (8\ \;10)\ $ is $\ q=5.\ $ Thus it's not true that $\ q\ge m$.

Consecutive primes versus prime twins
Indeed, I forgot that under the Schinzel umbrella conjecture a lot of more detailed conjectures (known earlier) would go against some of my attempts.

Cancellation law for $M^n\times \mathbb R= N^n\times \mathbb R$.
My private library is mostly gone, and I don't have a convenient access to a real mathematical library. I remember that one of the Borsuk major topological topics was the uniqueness of the topological cartesian decomposition. Later a remarkable paper about the uniqueness of the decomposition of finitedimensional ANRs into the 1dimensional factors (and a finite space) was written H. Patkowskaa student of Borsuk. Borsuk himself considered, among other things, the decomposition of manifolds into a manifold and a 1dimensional factor (I don't remember more, so sorry).
