Is this insectoid species realistic?

So I'm looking to make an insect-like organism for my book, and I was wondering what I need to think about to make it feasable, given these conditions:

-These insectoids are approximately 2 meters in height

-They have a standing stature

-They have lungs or similar breathing organs so oxygen is not an issue

-To accomodate for lungs, the armor is split into small plates that don't flex when the lungs expand

-Otherwise the insectoids have a covering exoskeleton just like insects do

Now I have a number of questions regarding this creature

-Would this be possible, and what other accomodations would I need to make to make it more efficient?

-How fast would it move, and what animals could it reasonably hunt given its speed?

Edit: Internal organs can all be modified as its only the look of an insect I'm really looking for
