agm batteries marine

Can I connect batteries in parallel to charge them with a single charger?
I have a deep cycle marine battery, an AGM motorcycle battery, and two other lead acid (i think) motorcycle batteries that I have removed from my summer toys for the winter and want to connect them all to a trickle charger for storage for the winter. I have one high quality battery charger ~1.5 amps that does all sorts of fancy battery maintenance voltage changes while charging, and another harbor freight battery charger ~.5 amps that I could use for tending these batteries. So my question is, will an arrangement, with each of these batteries in parallel and a low current trickle charger connected for winter storage work? Thanks.
No, definitely not, each one of your batteries has a different amperage rating and requires different charging rate for maximum output. Charge each battery separately.
