Can you elaborate more on step by step procedures upgrading Adv Cache 5.1.6 to 5.1.9?

Currently I am using 5.1.6 with selected patch below (Not all patches are applied)
- block
- comment
- node
- path
- taxonomy

And I am using Drupal 5.7.

Inside Adv Cache 5.1.9 I found out 5 subfolders named DRUPAL-5-6 to DRUPAL-5-10.
Is this means I need to apply only from subfolder DRUPAL-5-7? Since my Drupal is 5.7?

Or. Should I applied all the subfolders from DRUPAL-5-6 to DRUPAL-5-10 in sequence?

And additional elaboration on how to update Adv Cache itself in point view of DB...Is it automatically? I just need to replace all the folder?

Sorry if my question is too general...I am not so technical person.

Thanks
