We applied for ILR for main applicants in April 2020 but still awaiting a response. Now their dependants have completed 5 years and their visa is expiring soon, which means we have to apply now for dependents spouse and 5 years old child.

You need 2 years of cohabitation proof preceding the date of application.
Documents like tenancy agreement, council tax, water/electricity bills, bank statements etc.
Ideally documents should be in joint names but if not, you can top it up with solo names but same address. You need documents from 3/4 different sources which are evenly spread across last 2 years i.e. every 3/4 months.
Note: You must apply for them before their visa expiry even if you do not have a decision by then. Their application will be approved only after yours will be approved though.
The checklist generated at the end will tell you about documents. The main Tier 1 applicant’s details will be asked in the form when you fill out a SET(O) for your dependents. So their application will be linked to yours.
