You have too many brackets and braces... within filter syntax, there are
three ways to specify a value, using brackets, chevrons and braces, like
this:
[Tuesday] is a constant literal text value
<variable> retrieves the value of a variable currently in scope
{TextReference} retrieves the value from a text reference
Think of the brackets, chevrons and braces as different kinds of quotes
that indicate how the enclosed content should be handled. This is similar
to the way wikitext syntax uses [[...]] for literal links,
{{TextReference}} for transclusion, and <<macroname>> for variables/macros.
Note however that the filter syntax uses *single* brackets, chevrons, and
braces, while the wikitext syntax uses *doubled* brackets, chevrons, and
braces.
Thus, starting with your first example:
<<list-links filter:"[[Tuesday]next[Days of the Week]]">>
replace the [Tuesday] with {!!title} to use a TextReference to the title of
the current tiddler:
<<list-links filter:"[{!!title}next[Days of the Week]]">>
