That wasn't aid.
perfectly clear there was three explosion on the ship at 0:50
I just wonder what they transport and to where
That is the (single) explosion of the missile hitting the ship. You then see resulting fireballs emerge on both ends of the vessel. At the rear likely through the open deck area, at the front possibly from penetrating debris and residual missile fuel still moving forward.
Anyway, you can't really tell the cargo wasn't aid from that footage alone. For example, if it were aid, it could also include fuel(s), motorized transports, fuel tanker even (she was originally designed as automobile ferry with a large vehicle deck). Fuel is often part of aid, e.g. to power (hospital) generators And aid item such as milkpowder, sugar and flour could also yield a explosion. See 'dust explosions' e.g. in flour, dairy and sugar processing plants. Large internal (diesel) fuel tanks ensure that the ship has a long 4500 nmi range. In US service she was fitted with a large heli deck, and so there could also have been aviation fuel present.
It appears hangar and vehicle deck do not have solid door but some sort of curtains instead. She is built to commercial, not military/navy standards.

Elements of a Dust Explosion

Elements of a Fire:
- Combustible Dust (fuel);
- Ignition Source (heat);
- Oxygen in the air (oxidizer);
Additional elements needed for a Combustible Dust Explosion:
- Dispersion of particles in sufficient quantity and concentration
- Confinement of a dust cloud
Basically any combustible material and some considered non-combustible (your fuel) in the right concentration suspended in the air could lead to an explosion with potentially deadly consequences

I believe all five elements could have been present in this case ...
If it causes a caution on part of the navies of the GCC and keeps them from shore; I believe that is an achievement on its own.
That being said, I believe the issue occurred during DS and the presence of silkworm batteries by Iraq if I am not mistaken. If the GCC had slightly better fighting sense, sending that ship in those areas along with better intel would have had air ops carried out to first eliminate the SSM launchers before sending that ship into the area.
The GCC commanders have made the mistake of assuming that they are fighting just rag tag tribesmen whilst forgetting the well reported presence of Iranian intel and Iranian trained personnel within those ranks.
Once they change their gears towards a different fight, they will have much better success against the Houthi resistance and mop it up pretty quick.
This ship should doesn't have the sensors to detect an incoming missile (reportedly a C-802 or Iranian Noor variant), nor does it have any means, passive or active, of stopping one.
A Noor launcher is very diffcult to distinguish from a civilian truck, and it would be difficult therefor to detect its presence in an area in the first place. It has a range of between 30 and 170km, depending on version (Qader variant 200km). It doesn't need much more than a navigation radar to target.
