Yup.
Certian types of low karat gold may be alloyed with semi-precious metals such as silver, copper, iron or staimless steel. Also, white gold is sometimes alloyed with silver. The higher the karat of the gold, the less likely that it was alloyed with silver.
There is no naturally occurring yellow silver. Pure silver is a white metallic element, but it can be alloyed with other metals like copper to create shades of yellow.
German silver contains no silver content. It is another name for nickel silver which is copper alloyed with zinc and/or nickel. The name is confusing because it refers to the color of the metal rather than the actual composition.
Lead is less reactive than silver on the reactivity series, so lead will not replace silver in a single displacement reaction. Silver will stay as it is in the reaction.

All circulating US silver coins were at least 10% copper. Pure silver is far too soft, so it has to be alloyed to stand up to circulation wear.
All US silver one dollar coins from 1840 to 1935 contain 0.77344 troy oz of pure silver, alloyed with 10% copper for hardness.
Zirconium is an element - as are silver and lead. Therefore, zirconium is not silver nor lead and, conversely, silver is not zirconium, lead is not zirconium.
