Suppose my mom asks me to fetch her medicine. I don't know how many pills she is going to take. I take five and show her the pills that I'm holding in my hand. What would likely I say in this situation?
Is it enough?
Are these enough?

I would usually say
is this enough [medicine]?
She asked for medicine which is singular, or "some medicine" which is singular. Even if you are counting individual pills, I don't think you would use either of your examples above. You might just say something like:
how many [pills] did you want?
Are these enough?
Is fine.
Is it enough?
Is also correct, although a bit weird. It's far more likely you would hear natives say "Is this enough?" instead.
Both of your suggested questions are totally fine. "Is it enough?" asks whether what you brought (as a whole) is enough, hence the singular is fine. "Are these enough?" asks whether the number of pills you brought is enough, hence the plural is fine.
To be clear, you would definitely not use "it" in circumstances in which you single out the pills one by one, such as if you drop them (one, two, three, four, five) into your mother's hand. However, if you just grabbed a whole bunch of them and held them out on your palm, it is certainly fine to use "it" to refer to the entirety of what you brought to her. The best choice of words always depends on the context, which can include not only what you say, but also the circumstances and any non-verbal actions or gestures.
