Yes, they are sometimes called tappets too. Lifters and tappets are terms that are interchangeable. And also yes, lift them all up to be sure they move freely but don't worry if any fall back down as you are simply trying to make sure than none are stuck.

The clunk is worrisome though as it implies that something is physically broken. Maybe a thrown rod although the last time I had that happen (on a 1957 Ford Fairlane 500 2-door hardtop), it went out the side of the pan and block so was rather obvious. Still, there are other ways these can break and not be so dramatic! I hope it is not the case here but it seems to me that you are to the point where you should probably pull the engine or at least take off the heads.
