Is it true that two bodies fall simoultaneously in earth?

Yes, two bodies will fall at the same rate, if no other force such as air
resistance interferes. A feather and a hammer will not land at the same
instance here on Earth, but they did on the airless moon.

Does this fact prove the equivalence of mass inertia and gravitational
mass?

No.

This fact is more or less *called*
"the equivalence of inertial mass and gravitational mass"

Androcles is something that thinks that definitions can
be true or false.
And for some reason it never leaves a blank line to
separate his comments, so I have done that.
