They're called "harmonics".
The proper term for the lowest natural frequency of a vibrating object is the fundamental frequency. It is the base frequency at which an object vibrates and determines the pitch of the sound produced by the object.
Interesting question. By definition, the lowest possible frequency of a vibrating element is called the fundamental. That's the definition; it is what it is. However, the word fundamental and foundational are related, so you can think of the fundamental frequency to be the foundational one -- the one upon which all harmonics are built.
Timbre is the term that is defined as the quality given to a sound by its overtones. It is what allows us to distinguish between different musical instruments or voices, even when they are playing/singing the same note.

The term used for the measure of frequency is "Hertz (Hz)".
The definition of fundamental frequency is the lowest frequency of a periodic waveform. Sometimes fundamental frequency is abbreviated by FF, containing the lowest frequency starting from 0.

The term "multiples of 3" is a common math term. Children learn about multiples at an early age when learning to skip count. 3, 6, and 9 are all multiples of 3.
Fundamental in the long term, technical in the short term.
The term used for the measure of frequency is "Hertz (Hz)".
Different instruments having the same pitch will sound different because of overtones or harmonics, these are multiples of the fundamental pitch. A note plus its 2X harmonic and its 4X harmonic will sound different to the same note plus its 3X harmonic. This is called colouration.
When we do a Fourier transformation of a function we get the primary term which is the fundamental frequency and amplitude of the Fourier series. All the other terms, with higher frequencies and lower amplitudes, are the harmonics.
