Is there a way because I want to change the name from Donkey Kong to Shadow. But, I haven't found any file to change them. Does anyone know if it is possible?
Is this what you mean?
In the common5 file(common5_en.pac or common5.pac, depending on your setup), under "sc_selcharacter_en"(ARC), then "MiscData[30]"(BRES), then "Textures", scroll down to "MenSelchrChrNm.001"; this is where it starts for the names of the characters; export them, make sure to keep that size of the texture, edit it, then replace it with the replacement.
I don't know if this would work for the results screen or not, but it should.(I'm like 97% sure it'll work for the Character Select Screen character names, at least.)
The Results Screen names are handled in a very odd way. There is no file for Results Screen names.

This thread should give you what you need, since you can use codes to change the name of a character for the Results screen.
Edit: dang posted literally seconds before me.
