1 Does look like a Fer-de-Lance mimic but the rounded pupil gives it away as not that species.

2 One of the snail eating species or a Treesnake?

3 Seems to have tiny eyes, similar to Hydromorphus but no idea if they occur here.

There is a huge shortage of literatute in this area for snakes.

First should be Xenodon rabdocephalus, I think, cause of the round pupile and Fer de lance look like
 
Add another one from Pantanal


This looks good for Chironius quadricarinatus sp., eight upper labials, two posterior temporals, general appearance and locality encouraging.

A diverse and challenging genus. There is a wealth of (highly variable) pay-as-you-go literature out of which this may help : Phylogeny, diversity and biogeography of Neotropical sipo snakes (Serpentes: Colubrinae: Chironius).

Interesting thread, and thanks for posting, I'll have another look as time allows.

Here is what I think they are, I'm not a 100% sure though:

1. I would agree with Xenodon rabdocephalus

2. It's a Thamnodynastes, maybe chaquensis

3. Helicops leopardinus/polylepis

4. I would agree with Chironius quadricarinatus
