Spotting

I agree with bayucca & #1 is a female Argiope sp. - this species is sometimes called the "writing spider" because of the distinctive signature in its web.
Welcome to the community José!

I would probably separate them as individual spottings, this would help for ID, unless you are sure which ones were the same ones when you took the pictures.

#1 looks like an female Argiope sp. and above is the smaller male.
#2 might also be an Argiope sp., but different to #1 and #3.
#3 seems to be Argiope argentata, female, so again a different species.
That's how my eyes look at these cool spiders...
