These data indicate:

No. & Sex	Age Class	Therefore Born	Individuals Inferred
1 male	4 or under	1825-1830	= Charles (b. 1821/2)
1 male	10-14	1815-1820	= William (b. 1816/7)
1 male	15-19	1810-1815	= Daniel (b. 1810)

1 female	4 or under	1825-1830	= Nancy (b. 1824/5)
1 female	15-19	1810-1815	= Elizabeth
1 female	30-39	1790-1800	= Nancy (b. 1791/2)

Daughter A is either married or deceased.  I don't like the fit with son Charles, but then, census-takers do make errors.  Otherwise, the record is a good match for the family.

5.  1850 Census Index/Images (online at Ancestry.com; Image #6 of 90):  District No. 2, Todd Co., KY, p. 247A, 25/25, enumerated 24 Jul 1850 (extracted by Diana Gale Matthiesen):

Charles Mann	63	M	Ordnd M.E.M.	900	Va
Nancy L. "	58	F			"

Octavia    "	25	F			"
Nancy B    "	25	F			"
Isaac W     "	9	F			"
Elizabeth C. "	7	F			"
Nancy A      "	4	F			"

Mary A. is Wyatt's wife; Octavia is Charles Jr.'s wife; Isaac, Elizabeth, and Nancy A. are Charles Jr.'s children.  I'm guessing that Nancy B. is the daughter of Charles, Sr.  They are living next door to Isaac & Salina HUNTER on one side and Daniel & Martha MANN on the other.

There is a white male between 16 and 20 in the household.  Nancy is too young to have a son this old, unless she was lying about her age in the 1850 Census, which could very well be the case.  As expected, Charles disappears from the Christian Co. Tax Rolls when Todd Co. is formed in 1820.
