Yeah, they all mean the same thing, but some sound more realistic than others. The two best ones are: "I don't see him as more than a friend" and "I don't think of him as more than a friend." Native speakers use those the most. They’re super clear and sound natural. The ones with "beyond" are a little formal. You wouldn't really say them to a friend while grabbing coffee. If you want to sound even more casual, just say: "He’s just a friend" or "I don't like him like that." Hope that helps! Check out Urban Dictionary if you want to see how people talk about the "friend zone" lol.
