A devastating fire at the two rooftop pubs in Kamala Mills Compound in central Mumbai had claimed 14 lives on December 29 last year.
Additional Sessions Judge S V Yarlagadda refused bail to '1 Above' owners Kripesh Sanghvi, Jigar Sanghvi and Abhijeet Mankar, and Mojo's Bistro co-owner Yug Pathak.
The judge, however, granted bail to '1 Above' managers Kewin Baba and Libson Lopez.
The court had last month refused bail to Mojo's Bistro co-owner Yug Tulli.
The fire started because of charcoal embers flying from hookah, served illegally at Mojo's Bistro, and spread quickly, said a report of the MCGM's fire department.
Patrons could not escape because illegal alterations had blocked exits, it alleged.
