In this video from Russia, with translations, witnesses claim close encounters with alien type beings.  One of the witnesses include Russian Air Force officers and cosmonauts. .  The video also offers looks at claimed alien encounters from other countries. 

Reptilians (also called reptoids,  reptiloids, or draconians) are purported reptilian humanoids that play a prominent role in science fiction, as well as modern ufology and conspiracy theories. The idea of reptilians on Earth was popularized by David Icke, a conspiracy theorist who says shape-shifting reptilian people control our world by taking on human form and gaining political power to manipulate our societies. Icke has claimed on multiple occasions that many of the world leaders are, or are possessed by, reptilians attempting to gain power to rule the world.

Alien abduction narratives sometimes allege contact with reptilian creatures. One of the earliest reports was that of Ashland, Nebraska police officer Herbert Schirmer, who claims to have been taken aboard a UFO in 1967 by humanoid beings with a slightly reptilian appearance, who wore a “winged serpent” emblem on the left side of their chests

Grey aliens (also referred to as “Roswell Greys”, “Greys” or “Grays”) are alleged extraterrestrial beings whose existence is promoted in ufological, paranormal, and New Age communities, and who are named for their skin color.

Around half of all reported alien encounters in the United States describe Grey aliens. Such claims vary in every respect including their nature (ETs, extradimensionals, demons, or machines), origins, moral dispositions, intentions, and physical appearances (even varying in their eponymous skin color). A composite description derived from overlap in claims would have Greys as small-bodied sexless beings with smooth grey-colored skin, enlarged head and large black eyes. The origin of the idea of the Grey is commonly associated with the Betty and Barney Hill abduction claim, although skeptics see precursors in science fiction and earlier paranormal claims.

Nordic aliens are said by self-described contactees and some UFOlogists to be a group of humanoid extraterrestrials who resemble European racial images, or more specifically Nordic-Scandinavians.

Nordics are typically described as six to seven feet tall with long blond hair and blue eyes, and are commonly reported as being male. Their skin is said to range from fair colored to tanned,  they are reported to be in excellent physical shape, and they are sometimes described as wearing skintight clothing. During the 1950s, many contactees, especially those in Europe, reported beings fitting this description. Such claims became relatively less common in subsequent decades, as the grey alien supplanted the Nordic in most accounts of extraterrestrial encounters, but Nordic aliens are still occasionally reported. Some sources, such as UFO Contact Center International, refer to Nordic-type aliens as Pleiadians, referring to the Pleiades star cluster.
