Answer 1

Use a join and conditional aggregation:

select c.logo, count(*) as total,
       sum( status = 'new' ) as new,
       sum( status = 'repaired' ) as repaired,
       sum( status = 'consists' ) as consists,
from company c left join
     operations o
     on c.id = o.company_id
group by c.logo;

Answer 2

You can use below query as well,

select 
c.logo, 
(select count(1) from operation where company_id = o.company_id group by company_id) 
as Total,
(select count(1) from operation where company_id = o.company_id and status = 'new' 
group by status) as new,
(select count(1) from operation where company_id = o.company_id and status = 
'repaired' group by status) as repaired,
(select count(1) from operation where company_id = o.company_id and status = 
'consists' group by status) as consists
from
company c
inner join operation o
on (c.id = o.company_id);
