How could I get the count of rows from each table in a certain DB including the tables name? I know how to get the table count and the sum of rows for all tables, but not how to get the count for each table separately.

You could try something like this:
SELECT TABLE_ROWS, TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = 'DB_NAME'

If all the tables are inside a single database, let's assume it to be "test123", then you can use the following command to fetch number of rows:
SHOW TABLE STATUS
FROM `test123`;
It'll return result containing the following values:
`Name`, `Engine`, `Version`,
`Row_format`, `Rows`, `Avg_row_length`,
`Data_length`, `Max_data_length`, `Index_length`,
`Data_free`, `Auto_increment`, `Create_time`,
`Update_time`, `Check_time`, `Collation`,
`Checksum`, `Create_options`, `Comment`

I think this query resolve your problem:
SELECT ‘table1’, (SELECT COUNT() FROM Table1) AS CountTable1, ‘table2’, (SELECT COUNT() FROM Table2) AS CountTable2
