Imagine I threw something in space with a certain force, will it keep going forever in the direction thrown since there is no resistance? Or will it stop depending on the force?
Also suppose so much time has passed will the object still be floating (still moving a little bit here and there) or will it stand exactly still.

As usually, it depends. But assume you are in Earth’s orbit it will rather orbit Earth as weell, but ewen if you are at 400 km above Earth sirface there is Tiny amount of ait that will cause drag and eventually deorbit it. If You could throw it with velocity above 11km/s it could leave Earth gravity influence and strat orbit the Sun. If it is thrown with speed about 16km/s it could leave our solar system. For the velocities look for the 1st, 2nd and 3rd space velocity. And if you fly through the space it is very unlikely to hit anything. The space probes leaving Solar System and passing asteroids belt did not hit anything. Even if two galaxies collide each other it is very unlikely for two stars hit directly. The space is very, very, very,… big.
