There isn't any natural language composed only of vowels.
There are no words in the English language that have no vowels, other than non-standard words representing grunts.
The smallest number of distinct vowels (vowel phonemes) in any language is two. It is generally accepted that the Northwest Caucasian language Kabardian has such a vowel system.

Not necessarily. The so-called "long" vowels a, i and o make the diphthongs e+i, a+i and o+u respectively. Also, "long" u has a y-glide: yu
I can think of two, GYP-SY and PYG-MY.
Y is never a vowel. A, E, I, O and U are the only vowels in English language.
In English, the vowels are the letters a, e, i, o, u, and sometimes y. Vowels are speech sounds produced with an open vocal tract, typically forming the nucleus of a syllable. They are essential for forming words and conveying meaning in language.
The only US city with only vowels in its name is Aiea, Hawaii. Another city with only vowels in the name is Eiao in Marquesas Islands.
"a cappella," which specifically means singing without instrumental accompaniment.
All vowels (and y) in their correct order.
No. The Navajo language does not have the English vowel U. English does not have some of the Navajo vowels. Navajo vowels can be high tone or low or rising or falling if long. This change meaning in Navajo but only is used for questions in English. They can have nasalization which the French have but not the English. And they distingush between vowels held long or short which does not change meaning in English. See related links for a list of Navajo letters and sounds.
Phonemes are speech sounds, so a vowel phoneme is a speech sound produced by a vowel. Even though there are only five vowels in the alphabet, they are capable of producing different sounds. The English language has 44 phonemes out of which 20 are vowels and 24 consonants.
