No, it only costs if you wish to upgrade to the premium version.
No; that's why they are called "free" apps. Some are truly free. Some use ads to cover the cost of the app. If you want to get rid of the ads, you have to pay for an "upgrade". And some apps cost money and do not have a free version.
Joining Roblox is free but you have to pay if you want to upgrade to Builders club in order to make groups, get robux, join more groups etc.

Enchantment cost refers to the levels. Let's say you're level 32, and an enchantment you want costs 28 (which just so happens to be Silk Touch), you will have 4 levels left. In order to change the maximum enchantment levels, you must have bookshelves. The bookshelves must be at least one block apart from the enchanting table, and can be stacked up to 3 tall. The maximum is level 30, and you can cut off sources by placing a torch for a specific level. I hope this helped!
