Depending on the chemical composition, they can be partially or integrally dissolved or absolutely not attacked.
what happens
Nothing.
aluminum can melt by hydrochloric acid and it is creating as a bomb.
nothing
Because Hydrochloric acid is an acid, phenolphthalein would be clear. In bases Phenolphtlalein becomes pink
what happens

The temperature of the acid will increase
Well if you mix aluminum with hydrochloric acid, it will produce large amounts of hydrogen gas.
Nothing happens. They don't react.
Since Sodium Hydroxide is a base and hydrochloric acid is an acid, you will make water and sodium chloride.
You have to do an experiment
