Answer 1

Flush Magento Cache

This button deals with the main cache items for page display purposes. It can safely be used if you want to refresh your page.

"Flush Magento Cache" removes only those entries that Magento reliably tracks as it's own.

Removes all items in the default Magento cache (var/cache) and the var/full_page cache that have a Magento tag

Flush Cache Storage

This option is a more complete cache flush and includes more items in Magento's cache directory.

"Flush Cache Storage" clears everything but might affect other applications if they're using it.

Removes all items in the cache. This is the equivalent of deleting the entire contents of the cache folder on the server.If your system uses an alternate cache location, any cached files used by other applications will be removed.

Flush Catalog Images Cache

The Flush Catalog Images Cache option is just what it says. It deals with the catalog images. If you are changing images on products, and not seeing the new images on your site, you can try flushing this and refreshing your page.

Flush Catalog Images Cachebutton to remove all pregenerated product images files that are stored at: media/catalog/product/cache. If recently uploaded images aren’t visible in the catalog, try flushing the catalog and refreshing your browser

Flush Swatch Images Cache

Swatch images are resized and cached before they are used. Swatch images are stored on the server in the Magento installation directory, at the following location:

[Magento install directory]/media/catalog/swatches/

It is used to remove that resized and cached swatch images.

Flush Javascript/CSS Cache

This option involves a lot of the page styling cache and can be flushed when you are making updates. It is not needed regularly, but it is best to do if you want to see any recent changes.

Flush JavaScript/CSS Cache button to remove the Themes JavaScript and CSS files combined to one file from the cache. If recent changes to the style sheet or JavaScript aren’t visible in the store, try flushing the JavaScript/CSS cache and refreshing your browser.

Hope this make sense
