A lewis acid accepts an electron pair, while a lewis base donates an electron pair.

Bronsted/Lowry acids donate a proton and the bronsted/lowry base accepts a proton.

What about the Arrhenius definition of acids and bases?

Is a lewis acid/base always a bronsted acid and vice-versa?

Lewis acid is an electron pair acceptor and Lewis base is an electron pair donor. Bronstead acids are proton donors and Bronstead bases are proton acceptors.

Lewis acids are lone pair acceptors. Lewis bases are lone pair donors. Bronsted acids are H+ donors. Bronsted bases are H+ acceptors. Bronsted acids are most always the same as Lewis bases because they always accept a proton by donating a lone pair. Bronsted acids are a special kind of Lewis acid because the H+ part of the bronsted acid is the Lewis acid, not the whole compound, because only the H+ accepts a lone pair, not the whole Bronsted compound.

How are some molecules Lewis acids but not Bronsted acids?

Some molecules may be Lewis acids but not Bronsted acids because they have the ability to accept a lone pair of electrons, but do not have a proton to donate.
