How can I add "ALL" option on taxonomy filter?

For example I have 3 filters, then I want the 2 filters to show "ALL"

Hello,

I assume we are talking about shortcode [wpv-control-post-taxonomy] in the custom search form:
See our document:
https://toolset.com/documentation/user-guides/views-shortcodes/#wpv-control-post-taxonomy
There is a attribute "default_label":
'default option text'
Add default option like All or Any on taxonomy select control.

You can setup it within Views UI, for example, edit your post view, in section "Search and Pagination", edit your taxonomy filter field, there is an option "Label for the first 'default' option", see screenshot default-lable.JPG

But this option is only available for single choice options: "Select dropdown" and Radios, it won't work for multiple choice options:
Checkboxes and "Select multiple"

Is it possible to add none on the filters?

I have 3 taxonomy filters on the same page. How can they use only 1 or 2 filters without selecting also the 3rd?

For your new questions:

Q1) Is it possible to add none on the filters?
You can add a term "None" in your custom taxonomy, but don't assign any post to term "none", so if user select option "None" in taxonomy field of custom search form, Views will output empty result.

Q2) How can they use only 1 or 2 filters without selecting also the 3rd?
If the only use 1 or 2 filters, and without selecting also the 3rd (choose "Alll" default option in 3rd), this should be able to work as you expected without any problem.
