Not necessarily. A white dwarf is simply the remains of a low to medium mass star that has died. A red dwarf is a low mass star. Since red dwarfs last longer than medium mass stars, one could easily be older than a white dwarf.
A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.

White Hole - Red Dwarf - was created on 1991-03-07.
The correct order is red giant followed by white dwarf. A red giant is a stage in the life cycle of a star where it has expanded and cooled. After the red giant phase, the star sheds its outer layers and the core collapses to form a white dwarf.
Red (giant, supergiant or dwarf), Blue (supergiant), white (dwarf), blueish white/gamma-ray (neutron star) or produce no light at all (black hole).
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.

A stars evolution. Our Sun will go yellow dwarf -> red giant -> white dwarf -> black dwarf.
A white dwarf. Basically, a red dwarf just gets cooler and cooler until it has consumed all of its hydrogen. Then it becomes a white dwarf star. It will then dissipate any remaining heat into space and eventually become a "black dwarf".
Before a white dwarf, a star would undergo the red giant phase. After a white dwarf, a star may end its life cycle as a black dwarf, although no black dwarfs are currently known to exist in the universe due to the long timescales required for a white dwarf to cool down.
A white dwarf is the core of a dead star. As the star runs out of fuel, it expands into a red giant, as the shell of the red giant became a planetary nebula, and the core shrinks and became a white dwarf.
