Can only one of the two pumps in series be turned on?
Is there a bypass? It's okay to have a bypass.
No, the pump that has been under stress for a long time without its motor being started will have problems
It probably won’t work; since it’s in series, there must be requirements regarding the pressure at the inlet and outlet of the pump

If it is necessary to ensure that only one device reaches the destination, then one device can be used. It should usually be the first one to be turned on.
As long as one unit can meet the process requirements, it’s possible to use just one pump, which saves energy. If one unit is sufficient, the design should include cross-wiring.
Sure, use a cross-connected pump as a backup
If only one pump is in operation, the impeller of the pump through which the fluid passes will rotate in the reverse direction; if this reversal continues for a long time, will the impeller break off?
