The upper lens in a microscope is called the eyepiece or ocular lens. It is the lens through which the viewer looks to observe the magnified specimen on the microscope slide.

No, the eyepiece and objective lens are at opposite ends of the microscope.
The objective lens in a microscope helps to magnify the object being viewed on the slide. The objective lens can be rotated to change the magnification of the lens and yield a different view.
Zacharias Janssen's first microscope was called the "simple microscope" or "single lens microscope." It consisted of a single convex lens and was an early version of the compound microscope.

A simple microscope has only one lens.

The low power objective lens on a microscope is also known as the scanning lens.
a compound microscope has two or more lens while a simple microscope has only one lens
To change the magnification lens on a microscope, first, ensure that the microscope is turned off. Then, gently unscrew or detach the existing lens from the microscope. Carefully insert the new lens in its place and secure it in position. Finally, test the new lens by turning on the microscope and adjusting the focus as needed.

The arrow would likely point to the cylinder lens, which is the objective lens of the microscope. This lens is responsible for magnifying the specimen being observed.
