so these are likely not the only kind of squares in Indonesia (if you decide they are squares at all, or some of them), there will probably also be smaller ones.

seems so by this description, although festival grounds would typically not fall in the square definition IMHO.
I’m unsure about military parade grounds, but would tend to include them (thinking of central open areas used for mustering and surrounded by barracks)

You should get rid of the either or idea, they can be both (or squares can contain areas which are gardens, parks, maybe pitches. Actually I would exclude dedicated sports grounds generally but there could be exceptions.

within a village or maybe even hamlet yes, in the open countryside usually no.

I don’t understand this meaning of patio, can you post an example? A patio to me means an open space inside a block of buildings or within a building (inner courtyard)

It could have tall vegetation as a means of structuring it, or to separate it from surrounding streets, but this would usually be partial and allow passing.

Here’s an example of a square in Berlin in a residential early 20th century area:
It boasts all of the features you mention (scrubs, tall trees, etc.)
From my understanding, the square polygon would share nodes with the surrounding buildings, while the park/garden is contained, but smaller (the square minus the outer sidewalk minus the street minus the inner sidewalk).

I agree that these cases could eventually be questioned, one could argue they have been squares before and are now parks. I would still count them in, or we will end up splitting hair about how much of a square must be paved in order to be a square.
WRT pedestrian spaces, here’s the centre of Paris in a Nolliplan: http://www.iad-bs.de/site/assets/files/1954/schwarzplan.jpg
All the areas where the streets widen significantly at junctions with other streets are likely squares (you can’t see the smaller ones in this scale). The surrounding buildings will often accentuate the square (raised corners, main facade to the square etc.)
Usually there will be a relationship of streets and squares.
Another type of squares are those in front of significant/important/monumental buildings (e.g. churches, public buildings like town halls, train stations, parliaments, castles, ...)
