How can a diverse group of students who exhibit challenging behaviour be accommodated?

A mixed-age classroom with learners of diverse needs, with an age range of 9 to 11 years. One learner who is diagnosed with ASD and ADHD; another is dyslexic and hasn't received interventions when needed and now chooses distraction over work; one comes from a very unstructured environment and finds it challenging to work in a system; one has ADHD symptoms and also struggles in reading and writing but is great at math; two are good in English and math but are too lazy to do anything and just want to play and keep on fidgeting with things; two are neurotypical and can follow instructions and do things as expected. It would be really helpful to find strategies to be able to work in a common setting with these learners.
