If you're not using MySQL 8, this is a bit more complicated. First you have to find a path to a name element that has the value phone (or fixkit); then you can replace name in that path with count and extract the count field from that path; these values can then be summed:

SELECT param, SUM(JSON_EXTRACT(counts, REPLACE(JSON_UNQUOTE(JSON_SEARCH(counts, 'one', param, NULL, '$[*].name')), 'name', 'count'))) AS count
FROM data
CROSS JOIN (
  SELECT 'phone' AS param
  UNION ALL
  SELECT 'fixkit'
) params
WHERE JSON_SEARCH(counts, 'one', param, NULL, '$[*].name') IS NOT NULL
GROUP BY param

Output:

param   count
fixkit  9
phone   16
