No.

Epimers are sugars that differ in the configuration around one carbon atom. D-Mannose and D-Galactose differ in two carbons (C-2 and C-4).

yes.

D-glucose and D-mannose are epimers (difference at C-2), D-glucose and D-galactose are epimers (difference at C-4), but D-mannose and D-galactose are not epimer(difference at C-2 and C-4).

glucose and galactose are epimers because they differ in steochemistry only at one hydroxyl group. similarly, glucose and mannose are epimers, but mannose are galactose are not because their stereochemistry varies at more than one -OH group.
