Bang is an unit of mesurment that messure how much concentrations of Shinsoo one can control( i.e. one concentration or two seperate concertrations of Shinsoo), kinda like how many magical spells a mage can create at a time. How it shapes is irrelivent, and sometimes there is no shape to see( case in point Quant's black fish technique baams Fast Skip, each is a technique that uses one Unit of Bang to use) but its easier to understand them by shapeing them into 'sphers' since you can actually count them.

When Baam, and others with similar sttacks, gathers shinsoo into the sphears and then launches them he does it becasue its more effective to do that way because their more like beams of shinsoo while others are different.

How the Bangs are shaped are limited to the users specific prefference of style. Baam gathers them into one point then launches them, yihwa turns her Shinsoo into fire but the Bang is still there just looks different because she's a fire user. and Ran just simpally turns his Shinsoo into Electricity while creating the Bang.

Shinsoo is the literal name for the energy created in the tower, kinda like Mana but more complicated. all forms of elements are created from Shinsoo like Water and gas. if the concentraitions is light then its a gas and if its heavy then its water. theres no definit explanation for us at least since it is the direct energy created from the tower since there is no 'real' air and water in the tower(as far as I'm aware of).
