Depends on what you call a blood moon. It's the name for the red color during any eclipse and also the name for the first full moon after each harvest moon.
As seen from the earth, never.
It occurs every 5 months, twice a year.
They occur about once a year. Called perigee-syzygy or perigee moons by the astronomical community, they occur when a full or new moon (syzygy) is closest in its orbit to the earth (perigee), when the sun, earth and moon are aligned.
No. To get a solar eclipse the moon has to be in a position between the sun and the earth, this happens only round the time of the new moon (when there is little or no moon visible). When the moon is full, the earth is between the sun and the moon (there could therefore be a "lunar" eclipse).

Assuming you're asking how often a "half moon" appears, a half moon (First or Third Quarter moon) will usually occur every 14-15 days (half a lunar month).
red red
When Earth, the moon and the Sun are perfectly aligned. Not very often...
They occur about once a year. Called perigee-syzygy or perigee moons by the astronomical community, they occur when a full or new moon (syzygy) is closest in its orbit to the earth (perigee), when the sun, earth and moon are aligned.
The lunar cycle lasts 28 days.
