Roughing the Holder??? Personal Foul???

[BoBo]

A is lined up for a field goal. B22 rushes in and leaves his feet in an attempt to block the kick.

Play situations B22:

A- Blocks the kick but runs into the kicker or holder

Legal in both?

B- Does not block the kick but runs into the kicker or holder

Roughing the kicker 15 yards and auto first down?

C- Blocks the kick but B55 runs into the kicker or holder pretty much simultaneously with the block?

Legal by B55?

D- Blocks the kick but B55 pretty violently unloads on the holder (lets say he hits him high around the helmet for this situation)?

Roughing the holder or personal foul on B55 or nothing?

Just curious how you white hats would handle these scenarios?
