Most pitching wedges are around 48 degrees loft
56 degree loft
Taylormade pitching wedges are usually 48 degrees, however it can vary across different model ranges.
An approach wedge is basically a gap wedge (50 or 52 degrees of loft depending on model) This wedge is used when you are at a yardage which is between your pitching and sand wedge. You can also use this club for pitching, chipping and bunker play.
A U wedge is a utility wedge, i assume it is made by Ping. If so it is 50 degrees. If it is made by another company it is basically the same as a gap wedge, in which case it would have 50-52 degrees of loft.

As of Dec. 2008: Not all Taylor Made Irons sets carry an "A" Wedge. In all sets that do, the loft angle is 50 degrees. See: http://www.taylormadegolf.com/product_detail.asp?pID=227&section=specifications for the specifications page for the current "Burner Plus" model.
Loft may range from 19 degree to 60 degree depending on the specs of the iron.
Also called a Sand Wedge ... usually has a higher loft than what can be achieved with the "9" iron. Pro Golfers can have these custom made to their preferred angle of trajectory.
These clubs are usually made by Callaway, I have seen them in the Big Bertha sets. They are basically a pitching wedge. I would consider a 10 Iron to be more of a lob wedge. Mine is an old Spalding with a 60º loft, and hands down the best club in my bag. I have worked magic with that 10 iron.
