#1 looks to be the standard four blade, paddle blade you see on C-130s and P-3s, but that inboard prop is one of those new style. #3 and #4 are unknown.
What's interesting is that they (seem to have) mixed prop types on one aircraft.
The aircraft is a KC-130J. The C-130J models all have six bladed props. If you count fewer than six, that may be because one or more were knocked off in the mishap.
