MIN function exclude "Zero" values - Non Consecutive group of cells

With IF() we return FALSE if the value is zero, and logical value is ignored by MIN()

And just to add to the pot, an interesting small challenge:

Imagine range from large negative to large positive. We aim to retrieve the second smallest positive number from a discontinued range of cells. Hundreds of cells to take into account. The second smallest number retrieved (k) should not be equal to k -1, nor k +1. That is, a unique second smallest positive (non-zero) number.

See initial structure:

=SMALL(LET(continued,HSTACK(A1,C1,E1,G1,I1),FILTER(continued,continued>0)),2)

In the example, 8 should be the value retrieved and not 1.

Also, how to set the HSTACK or similar in an efficient way (hundreds of cells, cannot be entered mannually - one space between each one always).
