Edit your front page (In WP Admin>Pages) and add the shortcodes.
https://docs.woocommerce.com/document/woocommerce-shortcodes/
Examples ...
[recent_products limit="4" columns="4"]
[best_selling_products limit="4" columns="4"]
[sale_products limit="4" columns="4"]
[best_selling_products limit="4" columns="4"]
Change "limit" number and "columns" number to whatever you like ...
e.g ...
[recent_products limit="9" columns="3"] ... This will give you 3 columns and 3 rows with 9 products displayed.
[recent_products limit="12" columns="4"] ... This will give you 4 columns and 3 rows with 12 products displayed.
You will also have to put a title above each ...
e.g ...
Recent Products
[recent_products limit="4" columns="4"]
Best Selling
[best_selling_products limit="4" columns="4"]
... and so on.
If you install a slider plugin, you can insert the shortcode for that too.
