It takes a little bit of practice before it becomes natural to you, but acids are usually (not always) proton/hydrogen donors and bases are usually (not always) proton/hydrogen acceptors.
I'm not sure how much you know about organic chemistry, but when a hydrogen is attached to a molecule that would be more stable without it (I'm using the words proton and hydrogen interchangeably), the hydrogen atom won't mind leaving the molecule - making it an acid. An example of this would be hydrochloric acid (HCl). When Cl- is alone, it is happy, because it has a full octet of electrons. It doesn't need the proton attached to it.
If a hydrogen is attached to a molecule that would probably like another hydrogen, such as sodium hydroxide (NaOH), this molecule would be called a proton acceptor - a base. When Na+ OH- gets its proton (H+), it becomes H2O and Na+, a much more stable conformation of elements.
There are a lot of factors that go into it though; there are no easy rules for telling the difference between acids and bases just by looking at their formula. Some other factors that go into it: hybridization, resonance stabilization, and electronegativity.
Yes. All bases neutralise acids.
Acids have H+ while bases have OH-
Acids always tend to neutralize by reacting with bases.

Acids taste bitter.
Yes, concentrated acids and bases are more corrosive than dilute acids and bases
Of course they are. They are many acids and bases
bases neutralise the acids
Of course they are. They are many acids and bases
Yes. All bases neutralise acids.
acids and bases are important!
They don't dissolve (or more properly, dissociate) completely in water, only partially. Acids or bases that dissociate completely are called strong acids or bases.
Acids have a lower PH and bases have a higher PH.
Acids: H+ and Bases: OH-
