You don't spell it out except when discussing its phonetic use. Normally you just write F. But the phonetic spelling would be "eff."
The letter R is usually written as a capital R. The phonetic sound is ar or are.
The letter "Z" is least like the others (A, E, F) because it is the only letter that is not a vowel. A and E are both vowels, while F is a consonant but still shares more phonetic commonality with the vowels than the distinct sound of Z.
English is a partially phonetic language. While it is not completely phonetic, meaning that the same letter or letter combination can be pronounced differently in different words, there are consistent patterns and rules that determine pronunciation.
