1) Synapses can form between two dendrites,between
two axons, from axon to dendrite, from dendrite to
axon.  Synapses can form complex clusters, A on B
and B back on A; A on B and B on C and C on both
A and B, etc.

2) I don't really understand your question.  What do you
mean by "it"?  What do you mean by a "summed output"?
If the dendrite is near an electrically excitable portion of a
cell, it will certainly "see" an electrotonically conducted
fraction of the action potential.

3) No, a synapse cannot form on myelin.
