How to make two different versions of PHP (5.4 and 7.0) and Python 3.5 on one VDS if Nginx is used?

Question

PHP

Good day!
Due to the increase in appetite, some sites have to be transferred from the powerful bitrix-shared Timeweb to a third-party VDS (Debian 9 x64, by updating the distribution kit from 8.x Jessie). Please tell me how to properly organize this VDS in order to make the following structure:
- Python 3.5 (which comes out of the 9.x box, it runs two sites, Flask);
- PHP 5.4 (one very ancient and massive self-writing, it won't work on another version of PHP, checked);
– PHP 7.0 (site on Drupal 8 and Laravel 5.3);
All this economy should work through Nginx (I use MySQL / Postgres as a database).
I would like the change of PHP versions to be the most "painless" and one does not interfere with the other. Maybe it makes sense to make a separate VDS for each version with only the necessary version?
Thanks in advance.
