Need help identifying several prescription pills/medications.? Looking for information on 4 different pills.

The first is a large round yellow pill, about the size of a paracetamol, blank, no imprints, scored line through the middle on one side.

Second is a round maroon pill, slightly smaller than a paracetamol, blank, no imprints, scored line through the mid
middle on one side.

Third is an oval white pill, scored line through the middle, imprinted SL on the left and 60 on the right.

Fourth is a very small blue oval pill imprinted 0XB with 2.5 imprinted underneath. Other side is blank.

Any help much appreciated
