when to use tu,te ti?bcz all mean the samei.e. “you”

I’m sorry that I don’t know Spanish, but have prior knowledge of familiar languages. In the other languages they were used as you informal. In French and Italian both use the pronoun " tu". Italian uses ti as a direct object, for example: Ti amo. I love you. So by my experience French and Italian, I guess that all three words mean" you".

yes ,It refere to second person of singular .
Tú is used like subject.
Te direct or indirect object.
And ti is used after a preposition.
exemple:
Tú eres bueno. You are good.
Ella te quiere. She loves you.
Juan pregunta por ti. Juan ask for you.
See you.
