Explanation:

This compounds are very different each other.
Ammonia is a vapour but its polarity and its lone pair, that can react with #H^+# ion make it soluble in water in all the proportions.

Ammonium cloride is an ionic salt. All the salts of ammonium are very soluble in water . But not all the cloride are: for example Ag Cl, #Hg_2Cl_2# are very few soluble in water and also #PbCl^2# is few soluble in cold water. Other salts can be soluble or not with not always easy prevision.

#NHC_7H_13# may be a secondary ammina. Its solubility is quite hight if the Hydrocarburic part is quite small, because it can form Hydrogen bonds with water, but this isn't a small molecule so its solubility will be only about few g/L.

N_2 is an apolar gas and it is praticallly no soluble in water
