I want to get the number of target server that I have been scraping the metrics for. Can this number be dynamic? I mean if I add more servers, the number should increase automatically.

Thanks in advance!

You can get that with the PromQL query:

count(up) by (job)

If I am not wrong this will give me the number of configured jobs. But there can be more than one target server in a single job, hence, in that case it won't give the total number of target servers.

It gives you the number of targets per job. Usually servers will be in
one job, e.g. node.
