If i where to be in a position to advice anyone who just recently lost their job, i think the first thing i would tell them is to first relax and calm their thoughts. This is the stage where most people tend to get too anxious and in a hurry hence they end up making wrong choices. Once they have been able to clear their thoughts, they can pick up freelancing gigs like content creation or copywriting on sites like fiverr or upwork and the likes. Affiliate marketing would also be a good choice. One thing i would also remind them is not to assume they would start making money instantly.
