guest-session

After I saw this answer, I realized that there are many guest accounts on my system:

grep guest /etc/passwd
guest-jzXeRx:x:117:127:Guest,,,:/tmp/guest-jzXeRx:/bin/false
guest-l5dAPU:x:118:128:Guest,,,:/tmp/guest-l5dAPU:/bin/false
guest-FdSAkw:x:119:129:Guest,,,:/tmp/guest-FdSAkw:/bin/false
guest-eBU0cU:x:121:131:Guest,,,:/tmp/guest-eBU0cU:/bin/false

Moreover, in this moment there is nobody logged as guest, but if somebody will login as guest, a new guest account is created - why, since there are already other guest accounts? After the new guest will log out, his account will be deleted. But why the other guest accounts remain? For what use/purpose?

It doesn't mind me at all this guest account, but I want to know if it is okay to delete them manually.
