The spine is made up of several segments. It depends on what you mean by "lower" back bones. The lumbar vertebrae are generally considered "lower back", while the sacrum and coccyx make up parts of the pelvis.:
Cervical (7 bones) = neck
Thoracic (12 bones) = chest, vertebrae that have ribs attached
Lumbar (5 bones) = low back
Sacrum (one bone with 5 fused segments) = back of pelvis
Coccyx (4 bones) = tail bone - near the anus

its the coccyx (4) little bones right at the bottom of the spine
at the top its 7 cervical vertebrae
next is 12 thoracic vertebrae
then its 5 lumbar vertebrae
then its 5 sacrum(or sacral)vertebrae
then the 4 coccyx
sacrum and coccyx have no disc in between as these bones are fused together

I am standing on my head while writing this, so my coccyx is the upper back bone, and the atlas is the lowest.

I suspect you are talking about your sacrum, the lowest part of which is called the coccyx.
