[1] First retrieve all data from cell table
SELECT * FROM cell WHERE cell_id = :cell_id

[2] Now retrieve the related lc, dist and met
SELECT lc.* 
FROM lc l JOIN cell_lc c on l.lc_id = c.lc_id 
WHERE c.cell_id = :cell_id

[3] Retrieve the related dist
SELECT d.* 
FROM dist d JOIN cell_lc c on d.dist_id = c.dist_id 
WHERE c.cell_id = :cell_id

[4] Retrieve the related met
SELECT * FROM met WHERE met_cell_id = <met_cell_id from query [1] above>
