I heard in another documentary that there was around 90 discovered so
far.

That number depends heavily on how much deviation from a perfect sphere
you allow before you consider the body non-spherical. Btw, the
definition of planet doesn't require these bodies to be spherical, but
to be in hydrostatic equilibrium - which allows for rotational
ellipsoids too.

Are all sperical bodies going to be defined as "Planets" and
"Dwarf Planets"?

No - they are going to be defined as "Planets" OR (not and) "Dwarf
planets", depending on whether they've cleared their neighbourhood
(another fuzzy term btw) or not.

Or are some going to be left out? Is there a website
that lists them all? Thanks.

There are several such lists - some probably disagree with others.
Let Google find them for you.
