What can I do to fix my wood floors?

It used to be tight and have no spaces now there’s a few that look like this. I would not want to replace my whole floor hopefully.

You should not have that large gap, there is something wrong with the ends of that row of boards. You can use wood putty to fill gaps, if you have any boards left you can trim one to fit in the gap or buy a single board. You can also use cord to fill gaps but you need to prep first and stain the cord to same colour as flooring, then push into gap.
I would also look at re staining the floor, this will help where the laminate is lifting etc and also cover up the wood putty. There will be YouTube vids available for this.

Add plaster in the crack and then sand it down, then paint it brown

This looks like faux wood vinyl flooring? The ones that click together?

You should be able to just slide them back across where they should be. You could try using a bit of filler to keep them stuck together. Slide everything into the middle of the room and fill any gaps by walls or doorways
