Structurally logical schema according to the table

My colleague and I are preparing students for the NMT exam in Ukrainian language. We need a designer who can help transform our chaotic ideas into a professional system. What needs to be done: Create a visual style (color palette, fonts) that emphasizes our vibe: ironic, conversational, youthful, yet expert and neat.. Develop a set of templates in Figma (for summary files for various social networks, which will include explanations, tables, simple infographics, tests, tasks, information about our service with my colleague (NMT courses in Ukrainian language); we also need some visual accents).. The main requirement: the system must be convenient so that we can independently change the text in the ready-made templates.. We are a bit unsure about the colors we would like to choose for our project, so we would appreciate it if you could help us with this. We can send you our social media links so you can quickly glance at our "vibe" and suggest something cool. Our style: not sterile, lively, using memes and irony. I am attaching examples of our current materials to the project (the design is terrible because we did it ourselves, but there you will see what we need in terms of rules, tests, and you will also see our individual style of explanations). We would like our style to be visually recognizable and conceptual, with a twist. We often use interesting sentences (sometimes even with swearing or just jokes) in our work with students, so we stand out in the teaching market, and we would also like to have something individual in the files.
