Hanging from a bar will only temporarily cause a slight gain in height.
It's not that simple. You gain height when you gain height not when you eat spaghetti or rye bread.
You can generally put them where ever you want, but it the height placed at depends on the height of the person hanging it.
No. Just eat healthy and you will get as tall as it is decided in your genes.
Perfectly normal. For a girl, that height is average. Maybe if you gain 1 or 1 and a half inches, you will be perfect.
* Permanent height gain is impossible! Those who go into space, however, gain some height because of the lack of gravity -- but this is temporary. Sorry! Your genetics predetermines your height. * Some people thing that if you stretch every day you will gain height, but this is unlikely. However, if you learn to walk with a straight back, you gain height. * Perhaps use shoes with thick soles? Actually I think there are ways to potentially increase your size while you are still young and growing through diet and exercise (and maybe some risky hormone treatments). However, once you are full grown -- that's it. For more information, see the page link, further down this page, listed under Related Questions.

yes
Only temporarily and not by enough that anyone will notice. A humans height can vary slightly over the course of the day. Hanging might stretch you to your "morning height", but the difference is not noticeable to anyone not measuring you with a ruler. Excessive stretching can be damaging to the spine.
