What does maximum fuel per jump mean? I don't know if higher or lower is better and how it affects the gameplay.
Maximum fuel per jump has stopped me from jumping to systems several times so I want to understand how it works.

Reds are "hostiles".
If you're friendly with a faction that a ship is hostile to, they can show up red. If a ship is shooting at you, they'll show up red. If you shoot at a ship, they'll change to red (not sure if it's after they shoot back or immediate).
Assuming you're neutral (or better) and "clean" in a system, you can shoot at (and kill) a ship that is "wanted" and you can shoot back at (almost) anybody that fires at you first.
In other words, just because a ship is "hostile", it's not necessarily legal to fire at it. It's just likely to fire at you.
If you shoot at a clean ship, you will immediately get a (small) fine and become wanted (there will be a message about the fine in the upper right info area and a Wanted notification over your Fuel status area). Once you're wanted, it's legal for any ship to fire at you, and illegal for you to shoot back.
Probably what happened is that when you were firing at a wanted ship, one of your shots hit a clean ship, you became wanted, almost everybody became hostile, and you ended up with a large fine for killing a clean ship (or two or three of them?).
When you're in a crowded space, you really need to watch your shots and be careful not to hit any other ships. If you do unintentionally hit a clean ship, don't kill it (that will get a much bigger fine), don't shoot at any other clean ships, and run off to a station to pay off your fine/bounty quickly.
Note that ramming (or accidentally bumping) another ship counts as an attack.
Note that warning shots (firing but not hitting a ship) do not count as an attack.
Personally, I don't care for bounty hunting at nav beacons because they're so crowded and it's easy to accidentally hit a clean ship. I prefer to pick up a few tons of something reasonably expensive (look interesting to pirates with cargo scanners), and go for unidentified signal sources, being interdicted by pirates, or sitting in frame shift with the throttle low scanning ships until I see a wanted one that I can use my frame shift interdictor on. At the signal sources, it's common to find both pirates and a couple system authority ships, and in the other two cases it's likely system authority ships will eventually show up. However, when it's just a couple clean ships instead of a dozen, it's a lot easier to avoid accidentally hitting one.
In an anarchy system, there is no system authority and you can shoot at anybody. If you have a warrant scanner and warrant scan them before killing them, you can often get bounties redeemable in other systems.
If you're in a conflict zone, the rules are different. I think in that case, if you choose a faction (in the functions tab of the system/right panel) the opposing faction shows up red and there won't be any fines. I'm not sure, since the only conflict zone I've visited was one with only a single faction in it.
As cmdr Freiheit posited in comments, the integrity rating is an indication of how much damage a component can take before failing.
This was stated by Frontier Developments staff on the game's forum here: https://forums.frontier.co.uk/showthread.php?t=102717&p=1591966&viewfull=1#post1591966
"Also the [specific variant of module] has a higher integrity rating so that it can take more punishment before failing."

Higher is generally better, it increases distance of single jump by using more fuel (but fuel efficiency is decreasing if you use fuel up to the limit - the longer jump the more fuel is wasted). The standard upper limit is 5 ton per jump. Engineers can increase it a little (e.g. 5.21 ton per jump).
If you manually select some distant system in the galactic map (without building a route to it) and try to jump, you will receive the error about exceeding fuel-per-jump limit if the system is too far way. This can happen even if you have a route built - if you selected another system after route was built. You can assign a shortcut to ~"Select next nav system" and use it to re-select next-in-route system.
In general, economic jumps are short jumps, fuel efficiency is decreasing if you jump at biggest possible distance. Scenario when higher limit is worse is when you may need to re-fuel: if you build a multi-hop route which uses almost all your fuel (without re-fuel) with 5 ton-per-jump limit. Having bigger per jump limit means that you can make one jump less, but you will need to re-fuel due to less fuel efficiency of long jumps.
