What is the difference between bronsted acids and Lewis acids? Why do we need to classify acids differently?

I think they're two different acid-base theories; the difference is that a Lewis theory states that an acid is an electron acceptor and a base is an electron donor, and the Bronsted theory states that an acid is a proton donor and a base is a proton acceptor.

I think that a Bronsted definition of acids means that acids require a hydrogen (because a proton H+ needs to be released), whereas a Lewis acid means that some compounds without hydrogen can still be acids in certain reactions.

A bronsted acid is a proton donor. A Lewis acid is the species that accepts the e- pair. So, a Lewis acid is a broad term for anything that accepts a pair of electrons, whereas a bronsted acid is specifically the proton donor.

a bronsted acid describes acids as proton donors, as in they lose an H+. the lewis definition of an acid is that they are electron acceptors, so they gain electrons.
