>>> make a group of kids based on the first letter of their name and use the first letter as a name of their group. For example, a kid with the name rhythm, would be part of the group name R. Can you please show who all kids will be in the same group and what would be the name of the group?

Here is the list of groups based on the first letter of the kids' names, with the first letter of the group name also being the same:

Group R: Rhythm, Rihana
Group A: Aamir, Andy
Group B: Brent
Group D: Dave, Donald
Group A: Andre
Group M: Michael, Maryam

Therefore, Rhythm and Rihana would be in Group R, and the name of their group would be R.
