aggr and trunk are for combining two or more ports into a single uplink
(aggr only for LACP, trunk for various methods). Rither used to get more
capacity or to provide failover.
bridge (and theoretically switch but I never got it to do anything
useful) make a group of ports act like a network switch (maybe with
filtering between the ports).

These are closer to thw erhernet layer, IP is a separatr layer that
runs "on top" of this layer.
