Oman, Uzbekistan, Qatar and Kuwait progressed courtesy of respective wins over Syria, Hong Kong, Malaysia and Thailand.
Iran were given a first-half lead by Esteghlal defender Amir Sadeghi, and three further goals came the visitors' way prior to Mohamed Haidar's consolation.
Lebanon's defeat - combined with Kuwait's 3-1 win over Thailand - leaves Giuseppe Giannini's men battling for the best third-place finish and means Kuwait have reached their 10th Asian Cup as runners-up behind Iran.
Oman booked a third appearance in the tournament thanks to a 91st-minute strike from Eid Mohammed against Syria, while Abdulkarim Salem was Qatar's match-winner with a 65th-minute strike in Shah Alam.
Goals in the final six minutes from Vokhid Shodiev and Odil Akhmedov were enough to see Uzbekistan beat Hong Kong and confirm a sixth appearance at the final tournament.
Three sides who had already ensured qualification remain top of their respective groups after maintaining their unbeaten runs.

A goal in the opening minute from Mohamed Salmeen put Bahrain in control against Yemen, and Faouzi Aaish added a second with two minutes remaining to guarantee his side kept top spot in Group D ahead of Qatar.
Saudi Arabia - who have already won Group C - dropped points for the first time in qualification as China held them to a goalless draw in Xi'an, while Iraq kept their hopes of usurping China alive with a 2-0 win over Indonesia.
