How to query data from notes with a specific tag without knowing what data is written in them?

Good day to all.
Is it possible to use Dataview to:

  1. Find all records where there is, for example, the tag #check, then make columns with all the data that is in it.

Example:

In one record with the tag #check I wrote down the data:
number :: 5
Data :: 07/25/2024
In another record with the tag #check I wrote down:
Data :: 08/21/2031
Animal :: Cat
How can I request data if I don’t know what data I used (date, number, animal) when requesting?

*2) The second question with an asterisk, can I request only those data where the data format is equal to a number, and if several notes use data with the same name that denotes a number, so that they are grouped, and in the column, the sum of these numbers is displayed
