Are the default slic3r settings for sequential printing correct?
I tried sequential printing for the first time (Complete individual objects checked), but left the dimension paramaters default (20mm I think for both height and radius). I printed 2 figures a bit apart from each other, but my printer didn't print sequentially. It printed a few layers of the first figure, than the second and so forth, resulting in some gooey lines between the two figures. I thought slic3r would complain if you put two figures object to close to each together? I then put the two figures on opposite corners of the platter, and then it did print them completely separately. I have seen pictures of a sheet full of objects, very close to each other. I'd also like to maximize my productivity like that. Any tips how on how to handle this?

Sequential printing with a plate full of items is basically all but impossible unless it's a very small object. Each object needs a surprisingly large space around it to avoid having the extruder hit completed objects next to it, and the default r seems way too small (they should be r=60 or so, especially with the 45 degree fan mount. based on other info I've found - there's an open bug report asking to provide sensible defaults for the prusa profiles)
What's more, if your object is taller than the minimum distance to the X rods, you can't have any overlap of objects in the Y direction - otherwise the X rods will hit the completed object when printing the next one to its left. This is why you still saw it hop from object to object in your print despite having the setting enabled.
It's great for medium quantities of small objects so that can be spaced far enough apart - if one comes loose it won't scrap the rest of the plate of half-done objects, you can just cancel, retrieve the completed objects, clean up, and print what you still need.
It sounds like you have a stringing issue. You can improve on that by fine-tuning print temperature and retraction distances; most people just go with a little post processing from a heat gun or a craft knife to clean up the objects, if it can't be completely eliminated.

It were two miniatures of 28mm, but indeed, the extruder head occupies a large space. Thanks you for the explanation. Do you know if slic3r can give an indication if sequential printing will work or not given some models and its placement? I thought that is the reason why you could enter those dimensions.
Tbh, the stringing wasn't that big of an issue, and on single models I have no problem at all.
