There are about 450 mountain peaks over 7000 meters (430 peaks over 23,000 feet) tall. Most of these are located in the following mountain ranges: Himalaya, Karakoram, Kunlun, Hindu Kush, Hengduan, Pamir, Tanggula, Nyain'a. All of these ranges are in Asia, specifically in Nepal, China, India, Pakistan, Bhutan, Afghanistan, Tajikistan, Kyrgyzstan and Kazakhstan.
In fact, the tallest mountain peak outside of Asia is Aconcagua in Argentina that is 6959 meters (22,831 feet). That puts it at about 485th of the world's tallest peaks.
The highest peak in the whole world is Mount Everest at 8850 feet.

Mount Everest, between Nepal and Tibet.
29,035 feet.
Part of the Himalayas. Number two, I believe, is K2 in the same mountain range.
The claim to be highest has been disputed, but geological surveys support Everest as the best place to get high in the world.

Radhanath Sikdar, an Indian mathematician and surveyor from Bengal, was the first to identify Everest as the world's highest peak in 1852, using trigonometric calculations based on measurements made with theodolites from 240 km (150 miles) away in India. Before it was surveyed and named, it was known as Peak XV to the survey team.
The mountain is approximately 8,848 m (29,028 feet) high, although there is some variation in the measurements. The mountain K2 comes in second at 8,611 m (28,251 feet) high. On May 22, 2005, the People's Republic of China's Everest Expedition Team ascended to the top of the mountain. After several months' complicated measurement and calculation, on October 9, 2005, the PRC's State Bureau of Surveying and Mapping officially announced the height of Everest is 8,844.43 m ± 0.21 m (29,017.16 ± 0.69 ft). They claimed it was the most accurate measurement to date.[2]. But this new height is based on the actual highest point of rock and not on the snow and ice that sits on top of that rock on the summit, so, in keeping with the practice used on Mont Blanc and Khan Tangiri Shyngy, it is not shown here. The Chinese also measured a snow/ice depth of 3.5 m,[2] which implies agreement with a net elevation of 8,848 m. But in reality the snow and ice thickness varies, making a definitive height of the snow cap, and hence the precise height attained by summiteers without sophisticated GPS, impossible to determine.
The first measurement was with theodolites in 1856. Due to lack of access to Nepal at the time, it was measured from a distance. It was found to be exactly 29,000 feet (8,839 m), but declared to be 29,002 feet (8,840 m) high. The arbitrary addition of 2 feet (0.6 m) was to avoid the impression that an exact height of 29,000 feet was nothing more than a rounded estimate.
The elevation of 8,848 m (29,028 ft) was first determined by an Indian survey in 1955, made closer to the mountain, also using theodolites. It was subsequently reaffirmed by a 1975 Chinese measurement [3]. In both cases the snow cap, not the rock head, was measured. In May 1999 an American Everest Expedition, directed by Bradford Washburn, anchored a GPS unit into the highest bedrock. A rock head elevation of 8,850 m (29,035 feet), and a snow/ice elevation 1 m (3 ft) higher, were obtained via this device [4]. Nepal, however, did not officially recognize this survey, and the discrepancy with the above mentioned 2005 Chinese survey is significantly greater than the surveys' claimed accuracy.
It is thought that the plate tectonics of the area are adding to the height and moving the summit north-eastwards. Two accounts, [5], [6] suggest the rates of change are 4 mm per year (upwards) 3-6 mm per year (northeastwards), but this account[7] mentions more lateral movement (27 mm), and even shrinkage has been mooted [8].
Everest is the mountain whose summit attains the greatest distance above sea level. Two other mountains are sometimes claimed as alternative "highest mountains on Earth". Mauna Kea in Hawaii is highest when measured from its base; it rises over 9 km (5.6 mi) when measured from its base on the mid-ocean floor, but only attains 4,170 m (13,681 ft) above sea level. The summit of Chimborazo in Ecuador is 2,168 m (7,113 ft) farther from the Earth's centre (6,384.4 km or 3,967.1 mi) than that of Everest (6,382.3 km or 3,965.8 mi), because the Earth bulges at the Equator. However, Chimborazo attains a height of 6,267 m (20,561 ft) above sea level, and by this criterion it is not even the highest peak of the Andes.
The deepest spot in the ocean is deeper than Everest is high: the Challenger Deep, located in the Mariana Trench, is so deep that if Everest were to be placed into it there would be more than 2 km (1.25 mi) of water covering it.
The Mount Everest region, and the Himalayas in general, are thought to be suffering ice-melt due to global warming. The exceptionally heavy Southwest summer monsoon of 2005 is consistent with continued warming and augmented convective uplift on the Tibetan plateau to the north.
