Oh really?
@hellfire ?
Your hanooman air force will invisibly come and destroy our highly mobile nukes before they are launched?
Typical Indian wet dreams.
Your Prithvi sloth is a liquid fueled second world war era toy. It's very slow and can be shot with an air gun.
If your PCV, ABC or whatever you call it , can shoot a Prithvi in boost phase, not even terminal phase then that means nothing.
There is no requirement as such that necessitates bi conical RV. Agni 2 warhead is actually a tri-conic design.
In the final phase that is, when the RV is decelerating in atmosphere--something like 60kms till detonation, the speed of IRBMs like shaheen,ababeel or agni 2 reduced to 3-5 mach. You can run your own simulations in language of your choice either, matlab, python or julia --you'd end up with something like 3-5mach(more probably in the vicinity of ~3M at roughly 3-10kms altitude.
Only for ICBMs the decelerated velocity is in 5-7M bracket.Kindly note I'm talking about velocities below 10km altitude.
PS-I'm not talking about velocities just prior to entering atmosphere
Agni-2 may be penta conical but the missile is too narrow to carry more than one. Bi conical Design is to keep the warheads upright which otherwise will have to be tilted inward to fit in and will need extra machinery and maneuvers to fire them on target.

Bi conical design keeps the warheads upright,so yes it is a requirement for MIRV. For MREV it is not as the warheds can be stowed in tilted position and released at oncewith asymmetric thrust pyrotechnics which create some gap between them during and after release.
Agni - 2 may ne Penta conical but the missile is too narrow to carry multiple warheads. In fact no Indian missile currently has the right niose cone shape and width to carry MIRV.
Agni-3 and 5 are wide enough at 2 meters but Agni-3 PBV is too short to have any fanct maneuvering capabilities for dispensing MIRN and the Triangular / Conical nose is evidently not carrying anything more than one heavy Uranium based warhead.
In fact India hasn't demonstrated miniaturization of warheads on any of their missiles. There are no deployed Indian nuclear missiles which have visibly miniaturized warhead.
Brahmos doesn't count due to being a private company product and Russian. Nirbhay doesn't count as it is years away from deployment. Only candidate may be K-15 which may carry the smallest Indian nuclear warhead of 0.74 meter dia.
But even those cannot be MIRV on K-4.
About atmospheric deceleration of warhead. Thats not a problem unique to Pakistan, every nuclear power knows about it and does something about it.
Pakistan has significantly reduced warhead size and thus radar reflective area and less area for atmospheric friction. making it harder to detect Pakistani warheads and also maintain higher speed after re entry.
Other things can be done too, such as a gas generator at the back of the warhead which fires at randon, increasing speed at random intervals. that will make calculations very difficult for BMD radar. The BMD works on prediction. If a BMD cannot predict the incoming warhead's position accurately it will miss.
After the ABM is fired it goes towards a predicted point in space where the incoming warhead is predicted to be after x number of seconds. That prediction is based on warhead speed and direction observed by radars. Any change in those parameters will throw the calculations in the bin along with the ABM. Creating unpredictable behaviors in Missile RV is easier than most think.
