The challenge trophies will happen naturally while working towards the ‘Microphone Fiend!’ trophy above. All the challenges are basically variations of the songs with a different specific criteria required to finish the song (points, multipliers, timing, multiple songs, etc.).
With the 75-word challenges, they just take a lot of practice and a bit of luck as well. The Twista one can be intimidating but just practice it enough for the timing and you can mumble a lot of your way through it if you can't keep up with all the words. Just make sure your mumbling is fast enough that it still registers on one of the gold circles. The nice thing about these challenges is that the lyrics and pitch do not matter, it's all about getting the gold circles by any means necessary.
