How to wire two separate switches off one main 4-way switch
This is just a guess (see H-RM's comment), but if your intent is that the 4-way switches control whether or not there's power to the light switches at the bed, then this is no different from running wiring from 4-way switches to hardwired lighting fixtures.  You just install light switches inline with each lighting fixture so that power is toggled at the input to each of these 2 switches when one of the 4-ways is toggled.
This means that the 'logic' diagram will require both the correct toggling of the 4-ways and that either 2-way local switch be in the &quot;on&quot; position for the respective light to be &quot;on&quot;.  When the 4ways are toggled the other way, there's no power on the inputs to the local 2-way switches, so the lights would be off.
Warning: if you are not experienced in electrical wiring, get someone who is to help. It's important to know what is 'hot' and what isn't, and further to ensure the local 2-way switches (and their lights) are not in series.
