As far as I know:

"passthru" is used for ImageMagick/GraphicMagic to generate/process
images. Run the "Test Setup" function in the Install Tool to check.
"shell_exec" might be used by the scheduler and the RTE (e.g.
spellchecking).

"system" and "popen" is not used by the TYPO3 CMS core (as far as I
know). I don't know about "dl" and "proc_open".

Go to the Install Tool and run all checks in the "Test setup" section.
See if everything works, especially the graphic/image stuff.

At least the Extension Manager uses the PHP extension "zip". You can
possible live without that, but problems will likely occur when you
upload extensions in ZIP format manually.

Depends on your website, server load and server performance. The
officially *recommended* value is 240. Most sites likely work with 120,
too, though. Keep an eye on your log files if PHP timeouts occur.

> 4) PHP max_input_vars very low  --  max_input_vars=1000

The officially *recommended* value is at least 1500. Submitting large
forms in the backend possibly fail with max_input_vars=1000. If you get
a "security token" error message in the backend from time to time, you
should not be too surprised.

Contact your hoster and ask them to update the php.ini file, so that all
checks in the Install Tool pass successfully. If they can't (or don't
want to) provide an environment that meets the requirements, consider
using a different hoster.

The minimum requirements of TYPO3 CMS are not utterly excessive for a
professional PHP application today :-)
