The average person uses about 60 gallons per day (GPD) of water, but that number can vary by more than 50% depending on circumstances. I have metered systems for people who have very low production systems and seen them get that average down to under 40 GPD but to do it they are ever conscious of their low production system. As valveman stated, at 5 GPM yield well provides you with up to 7200 gallons of water a day, but only in ~5GPM max flow rates (once you deplete any reserve storage capacity of the well).
You can all but guarantee a reservoir storage system would satisfy the needs of the house and pool if the current system doesn't, but even a reservoir system may not be enough for your irrigation needs. If I were you I would spend some time learning about the water needs of your pasture and orchard to see if ~6500 GPD (7200 max GPD minus ~700 GPD needed for the house /pool/etc.) would be enough. If it is, then all you need to do is design a reservoir system with enough storage capacity to handle 7200 GPD. There are some additional convenience benefits of going to a reservoir system as well.
If you determine the well max production of 7200 GPD won't be enough for the property needs you could explore pond/lake options if the soil conditions are correct, and you can fill it with means other than the well, or you can look at drilling additional wells on the property to increase your max GPD capacity.
