There is no defined range of values in C. The built-in types all have ranges that are defined in <stdint.h>, <limits.h> and <float.h>. These ranges are implementation-defined, they are not defined by the language or by the standard. The standard only defines minimum guarantees such that a char is always at least 8 bits long (CHAR_BIT) and that an int is at least as long as a short which is at least as long as a char.
The range of char in C language is -128 to +127

Consult your limits.h and math.h. For char it will be -128..127 or 0.255 (signed and unsigned).
The range of character data types in C++ is the set of characters in the host's character set. It is inappropriate to consider the numerical range of such things as characters, because that depends on the particular codeset involved, such as ASCII, EBCDIC, UNICODE, KANJI, etc. Doing that leads to non-portable code, and lazy programming practices. Do not write code that depends on the collating sequence of the character set, or the numerical difference between two characters. Type char can be signed or unsigned, the value range is -128..127 or 0..255 respectively.
As integers, within range -128..127 if signed, 0..255 if unsigned.
An int and a char are both integral types such that a char is always guaranteed to be within the range of an int, because an int is at least as long as a short which is at least as long as a char (in bits). Converting the other way, from int to char, is not guaranteed to work, but we can guard against this by testing the int value is within the required range prior to conversion.The reason we use an int as opposed to a char in certain cases is because an int can represent values that a char cannot. This is useful in functions which would normally return a char value, but where we also need to cater for other values. Those other values could be used to indicate an error condition, for instance.
Yes, but this will result in an implicit conversion and possible narrowing. A char is always at least 8-bits in length, but an int may be 4 bytes in length (the actual length is implementation-defined) thus assigning an integer value outwith the range of a char will result in narrowing. Similarly when assigning a float (typically 16-bits in length); the fractional component will be lost and the integer value may be narrowed. An unsigned char is only guaranteed to hold values in the range 0 through 255 and a signed char is only guaranteed to hold values in the range -127 through +127. Any values outwith those integer ranges may result in narrowing. Most modern architectures support twos-complement notation thus the signed range becomes -128 through +127, however this cannot be guaranteed across all implementations. Also, a "plain" char may be signed or unsigned depending on the implementation but is a distinct type from an explicitly signed or unsigned char. A plain char is only guaranteed to hold positive integer values in the range 0 through 127 across all implementations.

yes because if you have categorical data you need the range for the value of the numbers so it would be the same for numerical data
Yes. They must have a range and median. They may or may not have a mode.
As integers, within range -128..127 if signed, 0..255 if unsigned.

'char a' and 'char a' are identical.
