One direct solution would be
Do[ Set@@{ToExpression["graph"<>ToString@i], Graph[cities, DeleteDuplicates@edges[[i]]]}, {i, imax}]
where imax is the upper bound on your index variable.
Alternatively,
Do[ graph[i] = Graph[cities, DeleteDuplicates@edges[[i]]], {i, imax}]
so that graph1 becomes graph[1], etc. Or, maybe even better,
graph = Table[Graph[cities, DeleteDuplicates@edges[[i]]], {i, imax}]
so that graph1 becomes graph[[1]], etc.
