Whits blood cells
Cells that identify pathogens and distinguish one from another are called antigen-presenting cells (APCs), such as dendritic cells, macrophages, and B cells. These cells play a key role in activating the immune response by presenting antigens to other immune cells, like T cells, to initiate a targeted immune response against the specific pathogen.
On human cells MHC molecules are used to identify cancerous cells. On bacterial cells things like LPS and various surface proteins are identified as "foreign" The problem with this is that not all molecules that are used to identify "friend or foe" are attached to the surface. Things like non-methylated CpG, LPS, peptidoglycan and dsRNA all activate PRRs in cells, leading to an immune response. If you want a more comprehensive answer please contact me.
They transform themselves to lots of plasma cells, which create antibodies to fight against the pathogens.
Cells of the immune system, such as macrophages and dendritic cells, mark pathogens for destruction by presenting antigens on their surface to activate other immune cells like T cells. This process helps the immune system identify and target foreign invaders for elimination.
Intracellular pathogens.

The type of white blood cells that can distinguish between different kinds of pathogens are called lymphocytes. They include T cells, which help coordinate the immune response, and B cells, which produce antibodies to neutralize specific pathogens. This ability to recognize and remember pathogens is essential for adaptive immunity.
Is to identify in blood or lymph. Or is to identify body cells that have not been invaded by pathogens. Or, to identify chemical mediators of immunity. Or, to identify pathogens in interstitial fluid. Or, to identify the activated macrophages.
Antibodies, the proteins that aid the immune system in recognizing and fighting off harmful pathogens, are produced by specialized white blood cells called B cells.
pathogens live inside the live cells
Yes. Antibodies do prevent pathogens from infecting other cells.
No. Hand sanitizers on your hands just kill pathogens (Pathogens is another word for germs, if you don't know what it means). The pathogens can't evade the alcohol. If they do, they may kill your brain cells. I do not know about other alcohols, but of course, it won't kill your brain cells if it doesn't have to do with killing germs. That was a very good question, anyway.

The immune system of the body provide a defense against abnormal cells and pathogens inside living cells. Generally this results into rise in temperature of the body. Therefore, fever is the indication of having war against abnormal cells and pathogens.
T cells destroy pathogens.
