For five days a week in only sleep for 4 hours and on the two other days I sleep for 8 hours, is this healthy?

Yes

No

No.

You cannot pay off "sleep debt".

Days that you lack sleep gets compounded, especially if you do it days in a row.

Permanent effects usually don't present themselves early, but why risk it.

No... not according to science. That being said I do about the same. Different time zones work
