Hello, I just want to know that can we use 2 Arduino IDE of different version program for operate 2 different router ?
Yes you can. You need to start two copies of the Arduino running. Not open one, and then open a 2nd sketch - has to be two instances of the IDE running, so that they show up as 2 icons on the task bar.
For example, this is IDE versiom1.8.4, with a 328P based board bootloaded as an Uno, and an actual Uno.
See the "portable" versions for that aspect.

That is a completely different question / issue.
I would suggest you start a completely different topic in the correct section with more details.
