My questions are:
1 Non stay of MM order- does it mean imminent arrest(when (a) the complainant had not named any witness as per requirement of Act and (b) police report which cleared me )
In the absence of registration of a FIR, there is no necessity to stay the proceedings at MM so soon or it is going to make any difference because there can be no arrest without FIR.
You can wait for the next date of hearing on this.
2 In case of FIR, what action can I take? What are the chances of such a legal recourse?
You can take anticipatory bail from high court and then face the case
3 In case of arrest, in what shortest time one can get bail? and the procedure please.
It depends on the court's discretion, you may get it in one day also.based on the gravity of the charges
4 being a govt servant , arrest is biggest worry though we have no objection to any investigation as complaint is totally false. How to safeguard this ?
Once a FIR is registered, you may go into hiding and emerge after anticipatory bail is granted
