I IV V are the most important notes in the 12 Bar Blues.
12 Bar Blues is a simple progression that is used very often in most rock and pop songs today and started back in the early days of Rock 'n' Roll.
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).
If that's a minor V moving to a IV chord, then no, it's not allowed. A minor V doesn't fit in anywhere in a major key, nor is V permitted to move directly to IV. To have a lowered 7th scale degree in the 2nd chord, leading to IV, try a V7/IV. It's a I chord with a minor 7th in it, working as a secondary dominant.
Not sure what you mean. If you mean a suspension chord, that is a chord made up of the I, IV, and V of a scale. For instance, a Csus is C, F, G. There is also a Sus 2 chord, which is the I, II, and V of a scale. A Csus2 would be C, D, and G. However, that is normally just called a 2 chord.
The "Primary" Chords in music are the three most commonly used chords. Those are the I, IV, and V (or V7) chords. Meaning the chords that are built off of the first, fourth, and fifth degree of a scale.
The I-V cadence should sound like the beginning of Twinkle Twinkle Little Star.

V comes after IV. ( IV means V minus I or the number before V.)
Rock Climb. It's HM08 in Generation IV, but just a normal move in Generation V.
IV is 4. V is 5
4 and 5 in Roman numerals are IV and V, respectively.
Roman numerals: 5 = V 4 = IV 1 = I I + V = IV.
They mean: V = 5 and IV = 4 respectively
Whats the main difference between V and IV as cadence chords?
I, II, III, IV, V, VI, VII, VIII IX, XI, II, III, IV, V, VI, VII, VIII IX, XI, II, III, IV, V, VI, VII, VIII IX, XI, II, III, IV, V, VI, VII, VIII IX, XI, II, III, IV, V, VI, VII, VIII IX, XI, II, III, IV, V, VI, VII, VIII IX, X
IV + I = V
I, iv, i, v, iv, i
