Replace data of a query with data of another table

[cherosoullis]

I have imported one table witch is split using queries. Later I have created another table with values witch represents values of queries wich needs to be replace with values of table. The attached file is reference. I dont know how to make the queries retrieve the values of the second table and update with them. Lets say that in a query a field with value "3333" wich meand "Giannis" as reference with the first table. I want the value to be change automatically but I dont know how to do this.
Maybe relationships will to the trick.
Can you please help me on this issue?
