Judaism
The Torah contains five books—Genesis, Exodus, Leviticus, Numbers, and Deuteronomy—which are collectively called the Five Books of Moses, the Pentateuch (Greek for "five containers", referring to the scroll cases in which the books were kept), or Humash (חומש, Hebrew for "fifth"). The book of Psalms is arranged into five books, paralleling the Five Books of Moses. The Khamsa, an ancient symbol shaped like a hand with four fingers and one thumb, is used as a protective amulet by Jews; that same symbol is also very popular in Arabic culture, known to protect from envy and the evil eye. Sikhism
The five sacred Sikh symbols prescribed by Guru Gobind Singh are commonly known as panj kakars or the "Five Ks" because they start with letter K representing kakka (ਕ) in the Punjabi languages Gurmukhi script. They are: kesh (unshorn hair), kangha (the comb), kara (the steel bracelet), kachhehra (the soldiers shorts), and kirpan (the sword) (in Gurmukhi: ਕੇਸ, ਕੰਘਾ, ਕੜਾ, ਕਛਹਰਾ, ਕਿਰਪਾਨ). Also, there are five deadly evils: kam (lust), krodh (anger), moh (attachment), lobh (greed), and ankhar (ego). Daoism

Other religions and cultures
According to ancient Greek philosophers such as Aristotle, the universe is made up of five classical elements: water, earth, air, fire, and ether. This concept was later adopted by medieval alchemists and more recently by practitioners of Neo-Pagan religions such as Wicca. The pentagram, or five-pointed star, bears religious significance in various faiths including Baháʼí, Christianity, Freemasonry, Satanism, Taoism, Thelema, and Wicca. In Cantonese, "five" sounds like the word "not" (character: 唔).
Under the FIBA rules, A player fouls out and must leave the game after committing five fouls
Five-a-side football is a variation of association football in which each team fields five players. In ice hockey:
A major penalty lasts five minutes. There are five different ways that a player can score a goal (teams at even strength, team on the power play, team playing shorthanded, penalty shot, and empty net). The area between the goaltenders legs is known as the five-hole. In most rugby league competitions, the starting left wing wears this number. An exception is the Super League, which uses static squad numbering. In rugby union:
A try is worth 5 points. One of the two starting lock forwards wears number 5, and usually jumps at number 4 in the line-out. In the French variation of the bonus points system, a bonus point in the league standings is awarded to a team that loses by 5 or fewer points. Technology
5 is the most common number of gears for automobiles with manual transmission. In radio communication, the term "Five by five" is used to indicate perfect signal strength and clarity. On almost all devices with a numeric keypad such as telephones, computers, etc., the 5 key has a raised dot or raised bar to make dialing easier. Persons who are blind or have low vision find it useful to be able to feel the keys of a telephone.
