In your example for Range 1, you are correct. That is the size of the memory, stated in hexidecimal, in bytes.
You may gain the most insight by first converting 00FF FFFF to a decimal number, then converting that number of bytes into megabytes.
To convert from bytes to megabytes use the relationship
1 MB = 1 Megabyte = 1024 * 1 KB = 1,048,576 bytes.
There are tons of online Hex to Decimal converters. The calculator built in to Windows can also do the conversion.
For the other ranges, you again want to do subtraction to determine the size of the range, and then apply the steps above, e.g.
FBFF FFFF
-
FA00 0000
---------
01FF FFFF
Having gone through those steps to better grasp what is happening, the following relationship will allow you to answer such questions faster:
0010 0000 = 1,048,576
So 1MB is the same as 0010 0000 (sometimes called 0x100000).

Solved: Can someone convert memory address (hex) into MB for me? | Experts Exchange
September 8, 2013 - To summarize: 1) Boot into 64-bit Linux, run these commands, and save the output: dmesg | grep e820 cat /proc/mtrr 2) Get the last memory address (from the first command). In the above example, it's 0x1AC000000 in hex, or 6848MB: [ 0.000000] BIOS-e820: 0000000100000000 - 00000001ac000000 (usable) 3) Compute the last address covered by write-back MTRRs (from the second command).

How to find out memory size by hex ranges? - Computer Science Stack Exchange
I read a memory-map ranging from certain hex values and I'm trying to find out how large RAM is by it. Here's the code: const char *memorybottom = 0x00000000; const char *memorytop = 0xAA55D0AB; The bottom is 0, and the top is AA55D0AB. I tried to convert that to binary and increased each 2 byte by a power of 2, left to right, but the result is 0.25 kilobytes; 256 bytes, which is 1/4th of a kilobyte. However, someone told me that AA55D0AB is for MB ... More on cs.stackexchange.com

February 24, 2020 - 16 MiB is then 0x100000 * 16 = 0x1000000 (add one 0 to the end. ... Also... OP's understanding of "decimal" vs "binary" is very ... weird and wrong. Decimal, binary, and hexadecimal are all radices (bases). The units of measurements of bytes has no bearing on this - you can represent 16MB worth of bytes in decimal, binary, or hexadecimal bases. The difference between 4000000 and 4194304 is the unit of byte counts - there's a Megabyte (MB), which is a number rounded evenly on traditional base-10 boundaries (10, 100, 1000, 10000, etc.), whereas 4194304 is a Mebibyte (MiB), which is rounded to a multiple of a power of two (usually a multiple of a power of 1024, which is a subset of a multiple of a power of two!).

the equation is
second_add - first_add + 1
example
fdff ffff - fd00 0000 + 1 = 0100 0000 = 2^24 = 2^4 * 2^20 = 16Mbyte [2^20 byte = 1 Mbyte]

Other writers use the convention of appending an 'h' or an 'H' to hex numbers. Thus FH = Fh = 15. 1 Kb = 1 Kilobyte = 1024 bytes. 1 Mb = 1 Megabyte = 1024 * 1 Kb = 1,048,576 bytes.

1 Megabyte is 2^20. That means that you need 20 bits to represent it. The range 00000-FFFFF holds all possible values of 20 bits.

It is well explained in pages describing the 8086 (the 8088 has the same instruction set architecture, but with slightly different pins).
Basically a segment register gave a (16 bits) base address which was multiplied by 16, then an 16 bits offset was added.
And 0xfffff is 220-1, i.e. 1048575
