I have this interpreter, which prints the ARGS variable:
#!/bin/bash
echo "[$ARGS]"
I use this interpreter in another script:
#!/usr/bin/env ARGS=first interpreter
Calling the second script, I get
[first]
How do I get
[first second]
?

The short of it: don't rely on being able to pass multiple arguments as part of a shebang line, and the one argument you can use must be an unquoted, single word.
For more background information, see the question @tholu has already linked to in a comment (https://stackoverflow.com/a/4304187/45375).
Thus, I suggest you rewrite your other script to use bash as well:
#!/bin/bash
ARGS='first second' /usr/bin/env interpreter "$@"
- This allows you to use
bash's own mechanism for defining environment variables ad-hoc (for the command invoked and its children) by prefixing commands with variable assignments, allowing you to use quoting and even define multiple variables. - Whatever command-line arguments were passed in are passed through to
interpretervia"$@".
