there are a lot of tools on github to deobfuscate not modded confuserex obfuscator and a lot of videos on youtube.

if you search hard enough you will find everything you are looking for.
solarpower is right, it is hex and you can convert it to a string and get the function's name but how would that help you?

functions' names are randomly generated to make it "harder" to deobfuscate.
