There are indeed two different segments by CNN and NBC that show an interview with two different men identified as the father of Amerie Jo Garza.
- It is clear that both segments are talking about the same girl with both segments showing a picture of the girl hold an honor roll certificate with her name here and here.
- The men in the different segment are clearly different people. Besides obvious appearance, the father in the CNN segment is identified as "Angel Garza", the father in the NBC segment is identified as "Alfred Garza III".
Contrary to the claim in the video clip from the OP, neither segment ever claims that either of the interviewed men are the biological father of the child. In fact, the obituary for Amerie Jo Garza states:

Amerie Jo Garza was a kind, caring, blunt, loving, sweet, sassy and of
course funny little diva who “hated dresses” but nonetheless; she
truly had a heart of gold. She loved to eat at Chick-Fil-A and vanilla
bean frape from Starbucks. Her favorite hobbies were swimming,
drawing, and most of all spending time with family. Amerie biggest
dream was to become an Art teacher due to her ambitions for
creativity. A protector of her brother and as we now know her
classmates. This world will never have another Amerie. She will truly
be missed.
(Bolding added for emphasis).
So, yes both men are the girl's father.
