Although all of them were taken using a DSLR camera, I'm certain the fourth pic can be done with mobile while the last one would require some enhancements in an editing software or app.
As for the rest I'm not sure, but I've seen pics like this that were taken by smartphone plus special lens... So maybe there are phone lenses now that can be used to produce similar effect of my pics 1-3
