Would the gravity be equal on all sides and crush you? Or would you float in the air and every small loose rock or anything else would be attracted to where you float?

You float without weight there.

you'd be pulled equally in all directions and float.
In physics class you may have studied gravitational force at a distance. It's an inverse square. Trying to type it here, it's
F = (Gmm)/r2 that last 2 is a square. This equation only works for above the surface of the earth.
BELOW the surface of the earth, it's not an inverse square. I don't remember the equation, it's not like it's used anyway, but I believe it's a linear function for the equation for gravitational force. Reason being, all the earth above you exerts a pull upward as well as the earth below you when you're burrowing down. When you're in the center, all the earth is "above" you and "below" you in equal amounts in all directions. You'd float. And be mashed by intense pressure. And be barbecued by the heat. Have a nice day.

Good question! Of course, the gravity that we experience here on the surface of the earth is really a short-hand summation of the gravitational force exerted on us by all the matter in or on the earth. Imagine every mote of dust, every drop of water, and every grain of earth and metal tuggin on you, just slightly.
As you move closer to the center of the earth, the -overall-* force of gravity would diminish, since the particles that are now above you are pulling you in the -opposite- direction, backs towards the surface! This would continue until you reached the center of the earth. Once you reached the theorotical "hollow center", you would fall towards the very center of the earth and presumably, you would oscillate back and forth, falling first one way, passing the center, and then back the other way, until you finally settled, essentially weightless, at the very center of the earth!
*at most points along the path, the force of gravity would actually increase, since you are now closer to most of the mass of the planet. However, since at the center, you experience no gravity, the overall change is towards less force of gravity.

I think you would float, because you would be right in the center, but you would be suspended up in the air because gravity would be acting upon you in all directions.
P.S. Any small, loose rock would be attracted to where you would be floating. Big, loose ones would too.

it is just like being in the spherical shell right . so anywhere in the hollow space you will not experience the force of gravity

Gravitational pull would be the same on all sides, and you would feel, in effect, weightless. Gforces would all cancel out.
