I have questions about future real conditional and future unreal conditional

There are a couple of sentences that I usually get mixed up.

1. If you try to take pictures of restricted exhibitions, a member of the staff will ask you to put your camera away.


2. If you are caught with food or drink inside the museum, you will be asked to dispose of it immediately.


3. If a person eats healthy foods like fruits and vegetables, It is more likely that they will be healthy.


4. It would be great if you could learn something every time you went to a museum.

I understand future real conditional and future unreal conditional like followings.

Future real conditional can be used in a situation where something is more likely to happen.

Future unreal conditional can be used when I'd just like to imagine and guess what it would be like if something happened or in a situation where something is impossible to happen.

And important thing is that it seems like I can use either of them in some situation because Future unreal conditional can also be used in imaginary situation.

1. If you tried to take pictures of restricted exhibitions, a member of the staff would ask you to put your camera away.


2. If you were caught with food or drink inside the museum, you would be asked to dispose of it immediately.


3. If a person ate healthy foods like fruits and vegetables, It would be more likely that they would be healthy.


4. It will be great if you can learn something every time you go to a museum.

So, can I use both of them in these 3 sentences?
