No. You have to lose a lot of momentum to slow down enough to survive the impact (obviously depending on the height of the building). In your scenario, you can only transfer that momentum to the chair, by pushing it downward with your legs.
Let's say you jump off a 10 metre tall building and have a mass of 75 kg. You will be travelling at about 14 m/s just before impact, with a momentum of 1050 kgm/s. You want to reduce that momentum to around 750 kgm/s (equivalent to falling from a height of 5 m, which is probably survivable and may leave you able to walk away), so you have to transfer 300 kgm/s of momentum to the chair just by pushing it with your legs. For a 10 kg chair that means accelerating it to 30 m/s (in addition to the 14 m/s velocity the chair and you are already falling at), which is rather difficult.
You'd probably be better off landing on the chair and hoping that the chair breaking absorbs enough of the impact.
The path the bowling ball would most closely follow after leaving the airplane is horizontal direction.
<h3>
Path of the bowling ball</h3>
Based on the law of inertia, which is the reluctance of an object to stop moving once in motion or start moving when it is at rest.
The bowling ball will maintain the path of the airline in the first few seconds of fall, after which it will change its path to vertical direction.
Thus, the path the bowling ball would most closely follow after leaving the airplane is horizontal direction.
