ext2 built upon ext1. ext3 is basically ext2 with a journal. ext1 is old. ext2 and ext3 are still widely used. ext3 is more reliable because of the additions of its journal.

I have never used ext1 but you can read and write files between ext2 and ext3 without any problems.

ext is obsolete. ext3 is similar to ext2 with the addition of journaling which makes it more rebust. When the number of reboots reaches a certain number, the system will run a check on it. This check will be much faster on an ext3 file system. The ext2 file-system is used for the ram-disk file, initrd, and often for driver floppy disks used during an install.
