May I suggest practicing shuffling 4 sheets with scrap film if it's your first time. You want to get your agitation method solid to ensure development uniformity, reduce the chance of scratching the film etc.
Alternatively, if you only have four sheets to develop, I humbly suggest doing one at a time. It will take longer of course, but doing a single sheet in a tray is about the best way to get really good, uniform development, and you eliminate manual handling of the film during development, which is always a plus. You can also use intermittent agitation. Lifting and dropping the corners and/or sides of the tray on a rotating basis provides excellent agitation.
Regarding developer volume, usually the manufacturer will quote a minimum amount of stock solution to develop 80sq inches of film, or a single roll of 35mm (or 120). This is equal to one 8x10 sheet. So to do 4 sheets (either together or individually), make sure you have at least 4x that amount of stock.
So using a developer like XTOL for an illustrative example, generally you need 100ml of stock per 80sq inches. So you'd technically need 400ml to do 4 sheets. If you were diluting 1+1, you'd need 800ml total solution (still containing 400ml stock). However more is usually better. And in the case of tray developing in an 8x10 tray you'd probably want around a liter of solution - even at stock strength. For an 11x14 tray you'd obviously want significantly more volume.
