No.
Music from Bob Wayne, Assjack and Wayne Hancock is similar to Hank Williams III's music. Perhaps even more similarity is found though in the music of Scott H Baram and Jayke Orvis.
The most important note of a chord is the tonic, followed by the third and the seventh, as they are what determines the quality of the chord (i.e. Major, minor, diminished etc.) Actually, the 7th only comes into play if it's a chord that includes the 7th. A major chord is the tonic, third, and fifth. A minor chord is the tonic, flat third, and fifth. A diminished chord is the tonic, flat third, and flat fifth. None of those chords (also several others) include the 7th.

You'll have to rephrase your question. There are no major keys in a chord. A chord is three or more notes sounded simultaneously. A major key is the set of notes in a major scale. There are chords within keys, there are no keys within chords.
When musicians use Roman Numerals for chords (like I, IV and V) that reffers to the scale step that the chord's root is built upon. The scale has seven notes that can be sung in solfege - "do, re, mi, fa, so, la, ti, do". Those same notes can also be thought of as scale steps "1, 2, 3, 4, 5, 6, 7, 1". So, when we replace these numbers with Roman Numerals, they represent the triads built on those scale steps: I, II, III, IV, V, VI, VII, I. If you want to be even more exact, you can show the tonality of the chords like: I, IIm, IIIm, IV, V, VIm, VII°, I for the Major scale and Im, II°, bIII, IVm, V, bVI, bVII, I for the Minor scale. Most popular music uses the three primary triads more than any of the others and those turn out to be the I, IV and V chords. In C Major that means the I chord is C, the IV chord is F and the V chord is G. In E Minor the I chord is Em, the IV chord is Am and the V chord is Bm or B (depending on which version of the minor scale you are using). So, when someone says "this is a I, IV, V tune" that means the piece will only use those three chords (and that it is probably based or loosly based on a blues form).
