The last two phases of the elections will be held on March 3 and 7.
Candidates contesting from Kunda (in Pratapgarh), Malhani (in Jaunpur), and Rasara (in Ballia) failed to secure enough votes to prevent forfeiture of their deposits.
State deputy Chief Minister Keshav Prasad Maurya among 692 candidates are contesting on 61 seats spread across 12 districts in the fifth phase.
Campaigning for the fifth phase ended on Friday evening, and all necessary arrangements have been completed, state Chief Election Officer Ajay Kumar Shukla said in Lucknow on Saturday.
The boy from Kanpur kept his audiences in theatres, on television and lately on social media platforms engaged with vivid societal sketches, be it about travelling in Mumbai's famous locals or lampooning queues at wedding buffets.
Chief Minister Yogi Adityanath who went on a whirlwind tour of the state to ensure the victory of his party candidates, described it as a "historic win". He attributed the victory to Prime Minister Narendra Modi's vision and BJP chief Amit Shah's guidance.
