According to an official of the Tourism Ministry, the climbers included a team of army personnel from the UAE and another from the Indian Army.
The official said that many other mountaineers on the expedition were on their way to the summit.
The climbers were stopped yesterday due to high winds but a clear weather from early morning today helped them conquer the peak.
Although the expedition to the world's highest peak opened on May 11, the expedition came to a halt for two days on Tuesday and Wednesday due to bad weather.
The weather today was favourable however, and many mountaineers were returning safely to the lower camps.
During the past six days the expedition was opened, 88 climbers including foreigners have scaled Mt Everest, the tourism department said.
In 2015, an avalanche triggered by a powerful earthquake killed 19 climbers and injured 61 others at the base camp. A year before that, 16 sherpa guides were killed by an avalanche above the base camp.
The recurring disasters on the mountain and deadly earthquakes last year had led to fears that climbers would be driven, but thousands of foreign trekkers returned this spring to Nepal, which has eight of the highest mountains in the world.
