Query output conditional upon values in dataset
If the number column contains values 5 AND 6, AND the value X exists in the chr column, I would like to exclude rows with 10 in the test column.
But, if the number column contains values 4 AND 5, AND the value X does not exist in the chr column, I would like to exclude all but ONE of the rows with 10 in the test column.

I am pretending your table name is number_table. You query can be divided into two separate ones -- the first excludes rows with 10 in the test column and the second includes only one row with 10 in the test column. I assume the two queries are independent. From interpreting your question, I believe this query will do the job.
SELECT * FROM number_table WHERE
(EXISTS(SELECT * FROM number_table WHERE number = 5 OR number = 6) AND EXISTS(SELECT chr FROM number_table WHERE chr = X) AND number <> 10)
UNION
SELECT * FROM number_table WHERE
((EXISTS(SELECT * FROM number_table WHERE number = 4 OR number = 5))
AND NOT EXISTS(SELECT chr FROM number_table WHERE chr = X) AND number = 10
) LIMIT 1;
