You can't refer to aliases in the same SELECT list. You need to put the query into a subquery.

SELECT col0, 
        col1, col2, col3, col4, col5, col6, col7, col8,
        col1+col2+col3+col4 AS total1,
        col5+col6+col7+col8 AS total2
FROM (
    SELECT CONCAT(extract(day from datetime_req),"_",extract(month from datetime_req),"_",
                extract(year from datetime_req),"_",`card_acceptor_id_code`,"_",`terminal_id`,"_",`ext_nserie_simcard`,"_",`ext_connection_type`) AS 'col0',
        COUNT(CASE WHEN `rsp_code_rsp` = '00' AND `tran_reversed` = '0'  THEN 'APROVADA EFETIVADA' END)  AS 'Col1',
        COUNT(CASE WHEN `rsp_code_rsp` != '00' AND `tran_reversed` = '0'  THEN 'NEGADA EFETIVADA'  END)  AS 'Col2',
        COUNT(CASE WHEN `rsp_code_rsp` = '00' AND `tran_reversed` != '0'  THEN 'APROVADA DESFEITA' END)  AS 'Col3',
        COUNT(CASE WHEN `rsp_code_rsp` != '00' AND `tran_reversed` != '0'  THEN 'NEGADA DESFEITA'  END)  AS 'Col4',
        SUM(CASE WHEN `rsp_code_rsp` = '00' AND `tran_reversed` = '0'  THEN `tran_amount_req` ELSE 0 END)/100 AS 'col5',
        SUM(CASE WHEN  `rsp_code_rsp` != '00' AND `tran_reversed` = '0'  THEN `tran_amount_req` ELSE 0 END)/100 AS 'col6',
        SUM(CASE WHEN `rsp_code_rsp` = '00' AND `tran_reversed` != '0'  THEN `tran_amount_req` ELSE 0 END)/100 AS 'Col7',
        SUM(CASE WHEN  `rsp_code_rsp` != '00' AND `tran_reversed` != '0'  THEN `tran_amount_req` ELSE 0 END)/100 AS 'Col8'
    FROM `table`  
    WHERE `datetime_req` BETWEEN '2019-10-29 00:00:00' AND '2019-10-29 23:59:59' 
    GROUP BY col0
