Lenses have two focuses, each on the two sides of the mirror.

Converging lens can have more than one focus depending on where the object is and focuses have to have same distance from the centre.

No lens has more than one focus and therefore no converging lens has more than one focus. It is important to understand here that every lens has two foci, one on either of its side and they are equidistant from the center of the lens. It can not happen that for a single lens, one focus in 5 cm from the center of the lens while the other is 4 cm.
