How do I rename separate folders to different solid names?

How do I rename separate folders to different solid names by batch?
For exsample:

1 - D
2 - H
3 - R
4 - P
5 - E

These results has no rules or orders, but the results are solid, I only and always need to rename them as D,H,R,P, and E.
Any ideas of how should I do it?
Thanks in advance.
