Each of these are mental processes, for example, Ti is the mental process of trying to logically make things consistent in your internal mental model, if you spend a lot of time trying to "proof" check things against eachother in your head by finding counter examples, then you're probably a Ti user
The T means thinking and the i means introverted. There's also Te which is the same but instead of checking against internal consistencies, you check against external data and principles, for example, people who try to justify moral actions against practical, results driven strategies are usually engaging in Te.
Both versions (introversion vs extroversions) of each function are quite similar to eachother but pretty dissimilar to others, like totally different mental "feeling" different.
Everyone uses all 8 functions, but the 4 shown in the above are the main functions that people learn to consciously call upon earlier in life, the other 4 only become developed after periods of self development or stress, in order to round out one's psyche which as Jung foretold, ultimately seeks harmony and balance.
Ti = logical consistency
Te = logical pragmatism
Ni = Intuition that reveals deep insights, think of it as "consciously seeing the subconscious", inductive, think schizo who's actually got a point
Ne = Intuition that reveals possible relations, very branching and deductive in nature
Fi = Internal values, the sense that something is inherently right or wrong (to put it simply), think "
Fe = external values, the ability to feel others emotions as your own, cognitive empathy that is felt not reasoned, think "reading the room"
Si = Internal sensation, the mental process of reading your own internal state, how your body and mind feels and reacts
Se = External sensation, basically the mental process of being one with the external physical word
Again, everyone uses all, but the top 3/4 are the ones you can consciouslly call upon easiest.
