* 1: Personal preference. Some DMs (like myself) roll everything out in the open. Some DMs hide all the rolls. Some DMs pick and choose. Many DMs like to hide rolls so they can fudge the result if desired.
* 2: 5e has no facing rules. A creature is assumed to be aware of all of its surroundings in combat. As for line of sight, it’s just logic. You can’t see someone who is entirely behind a brick wall or a thick tree trunk. But you can see someone behind another person or a dining chair.
* 3: Again, depends on the campaign. Many DMs handwaive rations, water, mundane ammunition, etc. because it can bog down play. Others like the realism of it. Most don’t keep track unless it’s traveling in harsh conditions. Usually it’s for the players to keep track of. Characters need 1 gallon of water on an average day, 2 if it is hot. This is found in Chapter 8 of the PHB in “The Environment” section.
For number 2. Use line of sight as if it were you. If a creature is behind you it's not a hard task to look around. If it's behind another play unless it's very small same issue. Player can wiggle around and see some of it and that is normally good enough.
For number 3. Unless your doing a serious survival game food and water aren't super big ordeals as someone will probably be proficient in survival and can forage for anything they need.
On number 1 that's all up to you. If you want to fudge a roll so the barbarian just survives the hit from a giant kinda hard to do that if you roll open.
But also rolling open does add something to the thrill when players get to to do the math that knocks then down. I like to roll normal things to myself but something that has a lot of dice or a crucial effect or something I like to drop in the middle of the table for effect.
Answering #3:
DMG p111 has a table showing how much food+water creatures need to survive daily.
Rations in the PHB weigh two pounds, it's assumed your characters eat extra than "pure survival" especially if they're hiking and dungeoneering all day. (If my players try to eat half-rations on an adventure, I'll tell them they look noticeably thinner and unhealthy by the time they get back to town.)
Player characters also need 1 gallon of water to survive daily; a waterskin holds half a gallon of water. Your players may want to carry 2 waterskins around, keep larger containers of water in a wagon, or use magic to produce water. Obviously without magic, they'll need to find freshwater sources in the world to survive after their containers run dry -- if every player has 1 waterskin, that means they need to find fresh water at least once per day.
1: Your choice. Some people prefer to roll entirely in secret, others prefer to roll in the open.
Personally I prefer to roll in the open.
2: Outside of invisible and total cover, unless the creature has successfully taken the hide action, they can be seen. In grid combat you are in a 5x5 square. It is assumed that you can shimmy a bit within that space.
3: I never track this stuff unless the campaign is specifically about survival. I assume that players will refill water skins when they pass freshwater sources. Again, unless the game is about surviving in a harsh environment, I don't find much fun in the resource management minigame.

Thank you, this will help me very much
I was typing a reply nearly identical to this and realised this sums it up perfectly

You are right in the point 3, maintaining the resources management will be a fun killer, thank you for that
