TL;DR Summary
I am trying understand a condition in a set notion.
Suppose f1,f2... is a sequence of functions from a set X to R. This is the set T={x in X: f1(x),... has a limit in R}. I am confused about what is the meaning of the condition in the set. Is the limit a function or a number value? Why?

I would have to say both. The condition "f1(x),... has a limit in R" is applied for one value of ##x \in R## at a time, so it gives a single value. But it is applied for every ##x \in X##, so that gives a function on ##X##.
