Explanation:

1. We use the suffix '-er' to form a noun indicating a person who performs an action. So "run" becomes "runner".
2. The prefix "im -" means "not", so "possible" becomes "impossible" to convey the negative sense.
3. The prefix "un -" means "not" or "opposite of", so "lock" becomes "unlock" to show the action of opening the lock.
4. The suffix "-y" means "having the quality of, full of", so "cloud" becomes "cloudy" to describe the weather condition.
5. The prefix "in -" means "not", so "visible" becomes "invisible" to describe air which cannot be seen.
6. The suffix "-ly" means "in a certain way", so "soft" becomes "softly" to describe how Noah spoke.

Answer:

1. runner
2. impossible
3. unlock
4. cloudy
5. invisible
