All sodium salts will give a yellow flame test, because of the metal sodium in the compounds.
It is a white solid that is soluble in water According to http://www.ilumina-dlib.org/browseRecord.asp?fileName=651-marc.xml&fileLocation=LiveData&sortBy=guid&orderBy=asc&taxon1=Chemistry&taxon2=&taxon3= it produces an orange flame
Because the color is due to the sodium. All of them have sodium, all of them give the same color. Technically nitrogen, oxygen, and chlorine have spectral lines as well; it's just that sodium's are much more prominent.
NH4Cl should not have an impact on a flame thus will emit a orange/yellow glow.
It is not the anions (e.g. iodide) that are responsible for the flame test color, rather the cations such as sodium ion, potassium ion and calcium ion give you different colors.

Copper II nitrate typically produces a blue-green flame when burned.
The yellow color of the flame is due only to sodium.
None. Using flame spectral analysis, we can use a prism or other device to determine the color of various metals. Nitrate gives no color. The purpose of the test is to give metal detection, qualitatively. Testing for nitrate is another test, not involving flame.

Sodium hydroxide does not produce a distinct color in a flame test. It is the sodium ions that give a bright, persistent yellow color to the flame.

Lithium nitrate and lithium chloride flame tests produce the same color because it is the lithium electrons that are raised to a higher energy level and then drop back down to their ground state. Any ionic compound containing lithium will give the same results. Flame tests are used to show the color and spectrum of the element as its electrons are raised to a higher energy level and then fall back to their ground state.
Alkynes do not produce a specific color in a flame test. Unlike some other elements and compounds which give characteristic flame colors, alkynes do not exhibit a noticeable color when subjected to a flame test.

Barium salts, such as barium chloride or barium nitrate, are commonly used to produce a green flame when burned. The green color is a result of the specific wavelength of light emitted by the barium ions during the combustion process.
NH4Cl should not have an impact on a flame thus will emit a orange/yellow glow.
