Escape Velocity

    If we provide a satellite with escape velocity perpendicular to the earth(radially), would it start orbiting it?

    No. Do you understand what escape velocity is?
    I'm guessing that you were shown escape velocity as it applied to a horizontal trajectory. But any trajectory that does not collide with anything will result in escape.

    If it is travelling at escape velocity, it is by definition not able to maintain a stable orbit and must eventually escape from the Earth's field of gravity.

    No, it would quickly disintegrate due to friction with the Earth's atmosphere.

    Disregarding that fact: No, if it has escape velocity or higher it will never return to Earth. If it has a lower velocity, it will (unless you change its direction at some point).
