9 shells, 3 Rubies, some 2D (and 1D!) languages and many languages I learned just for this challenge. I really enjoyed this challenge and learned some new languages and features. I enjoyed finding a shorter way than just the raw string in some languages (in some languages generating the string seemed longer) and trying to re-use the s variable as many times as possible was fun too. I've also tried to keep the byte-count as low as possible. If I find the time and the inclination, I wonder if I could start adding the letters of the alphabet to the end instead... Crazy talk...

goruby + --disable=gems
This isn't available on TIO, but is distributed with the official Ruby source and can be compiled (after the normal autoconf and ./configure steps) with make goruby. Tested on version ruby 2.8.0dev (2020-08-24T10:24:07Z master 1eb1add68a) [x86_64-linux]. The relevant code is:
s="ABCDEFGHIJKLMNOPQRSTUVWXYZ";0

The relevant code is:
¡72"8:é9:é8++:90+1®;65µ
This pushes the range of 1..72 and joins the last 8 items on the stack to a string, duplicates the top the stack, increments all codepoints by 9, duplicates the stack again, increments all codepoints in the string by 8, pushes 90 to the stack and concatenates all, reverses the stack, pop off the top 65 elements then prints the stack.

s="ABCDEFGHIJKLMNOPQRSTUVWXYZ";0
0//.../.__id__;begin ~:*&?,;puts s.gsub ?J,"";rescue;begin A;puts s.gsub ?G,"";rescue;puts s.gsub ?R,"";end;end
This shares the declaration of s with the shells and other Ruby implementations and and .gsubs J from the string before putsing it as long as ~:*&?, doesn't cause an error.

The main difference here is that $_OVM_PATH is set in OSH, but not in Bash, so the correct string is echoed using tr to remove the O.

The relevant code is:
s="ABCDEFGHIJKLMNOPQRSTUVWXYZ";0
0//1;
try:echo -n;print(s[0:23]+"YZ");
except:print(s[0:15]+s[16:]);"""..."""
This shares the declaration of s with the shells and Rubies and is also shared with xonsh. The code in the try will fail in Python (echo -n), but works in xonsh so the code in the except is called, printing slices of s.

The relevant code is:
('Q'⎕R'')⎕A⋄'...'⍵
In QuadR, when the final line contains ⍵ all the preceding lines are patterns to match and the final line is a transformation function. This particular transformation function just takes the alphabet ⎕A and ⎕Replaces 'Q' with '', the rest of the function after the statement separator (⋄) is just to close off all the other strings/comments/regex literals and comment out the end of the function.

The relevant code is shared with J-uby and goruby:
s="ABCDEFGHIJKLMNOPQRSTUVWXYZ";0
0//.../.__id__;begin ~:*&?,;puts s.gsub ?J,"";rescue;begin A;puts s.gsub ?G,"";rescue;puts s.gsub ?R,"";end;end
Like the other Rubies, s is shared from the shells but in Ruby here, both the other clauses ~:*&?, and A will raise exceptions so the final statement is executed which replaces R in s with the empty string.

The relevant code is:
0 65 65 if pop dup dup 83 sub if pop outputascii 0 fi pop 1 add dup 91 sub fi
This pushes 0 and 65 (twice) to the stack, then if (which is "while top of stack is truthy" - non-zero), pops the top element, duplicates the new top element twice, pushes 83 and subtracts it from the next stack item down. Then if top of stack is truthy (e.g. it's not 83 - S), pop it, outputascii, push 0 and terminate with fi (since top of stack is now 0). Finally, pop, push 1, add the two top elements together (increment), duplicate, push 91 and subtract, terminate the loop, which will happen if the last output char was 90 (Z).

"ZYXWVTSRQPONMLKJIHGFEDCBA"8 3*k,q
There are a few commands before this that are executed and push things to the stack, but basically this just pushes the required chars in reverse, then pushes 8 and 3 and multiplies them. The k command repeats the next command TOS (24) + 1 times, outputting the required string and quits.

The relevant code is:
<esc>ggdG¬AZ:s/V//"...
Which first leaves insert mode (<esc>), goes to the first line of text (gg), deletes to the last line (dG), inserts the letters from A to Z (¬AZ), then finally replaces V with the empty string (:s/V//). The rest of the line is commented out (").

The relevant code is:
...#220#1#1;.
..."ZYXVUTSRQPONMLKJIHGFEDCBA"#25&o @
The #220#1#1 pushes 220, 1, 1 to the stack, then ; pops off the last item then calls . which jumps the IP to line 1, char 220 and executes. We need to just because TacO mandates only one @ in the code.

xonsh is a Python based shell so the code is shared with Python 3 and uses the same s var as the shells and Rubies. I've used a technique I've used in many polyglots with Ruby to get this code in. 0//1 is integer division and the echo -n works fine since xonsh is a shell so the execution of printing the required substring portion of s with the literal string YZ concatenated, then the rest of the program is a """ string.

Like the other shells, but in yash, the sequence \e is not an escape sequence and so is just the string \e which matches e so $s is printed substituting Y for the empty string (${s/Y/}).

Zsh is less tolerant of errors in a script than the other shells and so necessitates the --continueonerror flag. In Zsh $status is also set (in fish too) when a command fails, so if $status is 1, then $s is echoed out, substituting Z for the empty string (${s/Z/}).
