"There are some really good friends who are always there for you."
Here's a breakdown:
* hay: "there are"
* uno amigos: "some friends" (the word "uno" is used in a general sense here)
* super buenos: "really good" or "super great"
* siempre: "always"
* pa ti: "for you" (slang for "para ti")
So, the phrase is expressing that there are good friends who will always be there to support the person being addressed.
