How does my character’s awakened mount and 2 awakened companions affect what CR the party can handle?

So some things happened and now I have 3 awaken scrolls. The rules say I don’t have to use material components so I can just use them. I also switch with the dm occasionally and run it myself. How would this character + their companion effect how much xp the party can handle? So, for balancing the CR of encounters, how does a lvl 5 optimized hexblade warlock riding an awakened Giant Crocodile with 2 awakened Giant Scorpions to their side effect CR?
