Is it possible that :- A constant force is acting on the body but it is still at rest...........
(no Friction, No Inertia)

yes it is possible that a constant force acting on body but body is still at rest,because to accelerate a body one requires net external force on the body,in your ques you are talking only about a constant force,but if more other forces are acting on body and their vector sum is a null vector then body is with zero acceleration.so if body was initialy at rest it will remain at rest.

EXAMPLE -IF A book is lying on the ground then it is acted upon by a constant force of gravity (due to its weigth) ,towards the centre of the earth but this force is balanced by the normal reaction due to the ground and hence the book is at rest..........
but according to your question --as the friction is absent therefore there cannot be any force which is applied and then also the body is at rest....

If you are on Earth and standing on the ground, then I can think of two forces acting on you. One is the gravitational force, which is the acceleration of your body that pulls you towards the center of the Earth. The overall force is the weight caused by your mass. (mg) The other force is the equal and opposite "normal" force, when you are in contact with the floor. It is in equilbrium with your weight and prevents you from accelerating, simply being pulled down the Earth. (N)
If you are in outer space and traveling at a constant velocity, then you have by no meanings any force acting on you, of course neglecting the gravitation of any other planets. In this case, there will always be a slight gravitation acting on you, unless you are thinking of a universe, where you are the only existent material with mass.

If a constant force is acting on a body (i.e. gravity) and another constant force of the same magnitude but the opposite direction (i.e. upward force from the ground) is also present, then the body will be at rest.
It is not possible for a body to have an un-ballanced force acting on it and to be at rest.

Yes, however if a body is at rest then there is no net force acting on it.

gravitational force act on body all the time but only in earth.

yes, 1.gravity
2.force due to air etc.,
acts on everyone everytime!

You mean, like, gravity?
There is no place in the universe where gravity is not present.
