The top one is a silver mohar from Nepal, dated 1827 Saka Era (AD 1905). https://ngccoin.com/price-guide/world/nepal-shah-dynasty-mohar-km-651.2-1826-1833-cuid-1084899-duid-1437171

Coin number 2 is not a coin, but a Hindu "temple token", also known as a "ramatanka". The giant earlobes on this piece tell me it is a late 20th century base-metal mass-produced example, rather than an earlier silver specimen. See examples here: https://zeno.ru/showgallery.php?cat=3249

Coin number 3 is also not a coin, and also an Indian "temple token", though this time is is for the Sikh faith, not Hinduism. Examples here: https://zeno.ru/showgallery.php?cat=3373
