yes, just different names
No.
A sleeve bearing relies on contact to support the load. These bearings can carry large loads for their size and cost. But, they are very limited with regard to speed. They are also the best bearing for joints that do not turn a full 360° or continuous rotation. Example: Door Hinge
A journal bearing relies on a film of oil to keep the two parts from making contact. They work on a dynamics basis; that is the rotation of the journal (shaft) pulls the oil through the high pressure zone via the viscosity of the oil. Unlike sleeve bearings, journal bearings like speed. They do not do well if they are moving too slowly. They are the most durable bearing known. Example: Engine crank shaft, piston connecting rod to crank.

Shaft revolving in a bearing which pair?
If it is ball bearing, it is of higher pair. since the balls in the bearing have point contact with the surface. if it is a journal bearing, it is of lower pair. since the jounal is having surface contact with the shaft. This question refers to the type of pairs in a mechanical joint...

What is adapter sleeve and withdrawal sleeve?
The adapter sleeve is typically used when the bearing is on a shaft without a shoulder and needs to be placed properly in a pillow block housing for example. This sleeve uses a hydraulic or mechanical device or nut to tighten the bearing on the sleeve and hydraulic oil injected into the end of the sleeve on larger sizes to release bearing when removing. The withdrawal sleeve is used when the bearing is installed against a shoulder on the shaft and pushes the bearing against the shoulder while tightening. The advantage of this is the bearing can be installed with the shaft out of the machine since it is pressing against a shoulder, with the adapter sleeve, it would be more difficult to position the bearing with the shaft out of the machine since it is free to move on the shaft until it is tightened. The choice of which to use will depend on the design of your shaft and how it will be installed. The attached document shows the mounting and dismounting methods of both sleeves and will probably answer many of your questions.
