Restriction is limitation as in speed restrictions.

An inhibition is something which prevents you from expressing yourself freely or from letting yourself go: get rid of your inhibitions.

Prohibition is forbidding (especially the sale of alcohol) – telling someone not to do something.

Condition can mean state: the bicycle is in very good condition; weather conditions are appalling. It also means ‘term' (of a bargain): he will come on condition that we let him pay, provided that we let him pay; there are various conditions attached to the agreement. Another definition is ‘bad state’: she has a heart condition, she has a weak heart.
