This works for the example given but it introduces other question like how to create the list {HoldForm[ts2], HoldForm[ts3]} apart from typing it in. Typically you would start with an expression of held Symbols before they (ts2, ts3, etc.) are assigned values. Another question exists that addresses the use of this form to some degree: Elegant manipulation of the variables list Nevertheless IMHO this should not be used commonly but rather as a special purpose tool.

To do this you can separate the names from the data using indexed objects, Rules, or Associations. Instead of defining ts1 = TimeSeries[. . .] you would would instead write one of the following:

The question at face value

To leave no stone unturned I should address the actual question as asked rather than only proposing an alternative. You can HoldForm the individual Symbols in the Table and then ReleaseHold that expression when you need it to resolve to the TimeSeries:

Table[ListPlot[Transpose[{ts1["Values"], ReleaseHold[i]["Values"]}], Frame -> True, 
  FrameLabel -> {"ts1", i}], {i, {HoldForm[ts2], HoldForm[ts3]}}]
