I played with it a little bit to get the hang of it.
I hit a roadblock as soon as I replaced "1 2 3 4 5" in the nested for loop with "animals fruits drinks cities countries". I tried it in 2 ways but got the same result in both attempts. I also tried putting
I had also tried the following and still got the same results:
At least this alternative works just fine:
Is there a way to make it work with all=(animals fruits drinks cities countries) ?

I hate to say it, but: this was to be expected. What you tried was a so-called "associative array". This is an array where the index is not numbers but (arbitrary) strings. There some programming languages which offer this kind of arrays (awk, for instance), but not bash. You can use ksh93 (Korn shell in its '93 version), which does offer such a functionality, but not bash or ksh88.

Lets see. I warn you beforehand, this is more a workaround, not really a solution. Consider the following sample script:

As much as I hate to say it: ever since version 4 (which the OP seems to run), bash HAS associative arrays:
man bash:

Arrays
Bash provides one-dimensional indexed and associative array variables.

Associative arrays are created using declare -A name.
You need to declare / typeset them correctly, though ...
I've been spending some time trying to have a column-wise output, as opposed to row-wise as in your example, but most importantly target specific items in each "array" as well. All while typesetting everything the way you did. Here is what I came up with:
Here I hardcoded k but I do have a way in my actual script to increment it. As per the output below, I am getting the 2nd item of each array as expected but their order is somehow incorrect
k=3 outputs the same [incorrect] pattern:

Bakunin: Thank you as well! But why is it "not really a solution"?
As with RudiC's solution, I'm outputting column-wise and hardcoded $y to target a specific index, but this time the order is correct:
Yes I'm using version 4 both at home and work, though I don't have the luxury of using typeset -n at work.

I fixed the order! I just had to change the for loop
