How to I use $value > n, $value < n, to show only the option it applies to?

I am using twine 2, or the online version, How do I make it so that when I want this to happen.
$value < 5 only option 2 appears and is select-able.

You need to state which story format you are using, as answers can be different for each one. I am going to assume you are using Harlowe, which is the default.

You can use the (if:) and (else:) macros to control what gets displayed to the Reader.
note: I add indentation and line-breaks to make the example more readable, you can remove them.

(set: $value to 4)

(if: $value < 5)[
	[[Option 2->Target Passage Name]]
]
(else:)[
	[[Option 1->Target Passage Name]]
	[[Option 2->Target Passage Name]]
	[[Option 3->Target Passage Name]]
]

... changing the $value to 5 will display three options.
