I am really bad at identifying spiders, so while I tried, I am not sure I named them right.
This huge one lives under the roof of our outhouse. It might be a "she" as there is a big web sack in a corner.
The closest by looks is a Phalangium opilio, but Wiki says they are not spiders and don't have silk glands, while this one has them and weaves a round web to hunt.
This one is really tiny, about 2-3 millimeters.
It is a crab spider, most likely a Diaea subdola
Closest I could find for this one is Neoscona adianta, a kind of orb-weaving spider. They are really common in forests here, but most of the time you see their webs, not spiders themselves.
This one is likely some kind of a Wolf Spider, but there are so many of them that I couldn't narrow it any more. Or as I was corrected and Wolf spiders don't climb flowers, it can be Jumping spider.
