Is there a way to strip all the electrons from single atom with atomic number greater than 2

Please explain by what means electrons extraction can be done.

Hot enough plasmas have all the electrons in the plasma leaving the nuclei positive.

How person can focus activity on single atom (from precision point of view) to do so?

One cannot deal with individual atoms. It is a statistical phenomenon and one can get a beam of ions without any electrons from a plasma, as is done in the link provided by CuriousOne.

How at each step person can know how much electrons have been removed till now

See above. Plasma is a phase and is a thermodynamic state. 

A plasma can be created by heating a gas or subjecting it to a strong electromagnetic field, applied with a laser or microwave generator. This decreases or increases the number of electrons, creating positive or negative charged particles called ions, and is accompanied by the dissociation of molecular bonds, if present.

If one wants completely stripped nuclei from electrons, a fully ionized plasma, one has to have a high enough temperature .
