It's OK to have a bigger squat than the other lifts, and it's one of the best exercises anyway.
I've been doing 5x5 for more than a year now, and my lifts are exactly as PravinCG said : DL > SQ > BP > BR > OHP.
But I did not follow exactly the plan : I added 5kg for the deadlift until I reached 160kg (instead of 2.5kg after 100kg), otherwise I guess my deadlift would be closer to my squat.
Don't try to catch up, be humble, and don't hesitate to drop weight when you miss a few sessions. When I miss a week I drop the weights as many sessions I missed, it's just a way to make sure your form is perfect, because let's be honest : when you add 2.5kg to your best lift every time, at some point your form won't be as good as before. Even if my 5x5 curve is sometimes flat, I warm up heavier than a lot of guys in the gym, so don't worry about catching up : take your time, you'll be strong.
