The following (tested) shows how to do this. You define a separate 
series of footnotes (TitleFn below) with its own counter (TitleFnCount) 
that functions independently of the default footnote series. You also 
define the symbols you want to use for that series (TitleCS). (Note that 
the second argument for defineconversion should be a list, so [×] will 
not work, but [×,] will work. Color is shown for the second flag so that 
it stands out if you accidentally make a second TitleFn.)

You can also reset the counter, as shown in the last couple of lines.

    \setuppapersize   [A6]

    \defineconversion [TitleCS]
                       [†,{\color[red]{‽}}]
    \definecounter    [TitleFnCount]
                       [way=bytext]
    \definenotation   [TitleFn]
                       [footnote]
    \setupnotation    [footnote]
                       [numberconversion=set 2,
                        indenting={yes,small}]
    \setupnotation    [TitleFn]
    [numberconversion=TitleCS,
                        counter=TitleFnCount,
                        indenting={yes,small}]
    \starttext

    This  sentence has a title footnote.\TitleFn{Title}
    This sentence has a regular footnote.\footnote{Footnote}
    And this sentence has a regular footnote.\footnote{Footnote}
    This is a second sentence with a title footnote.\TitleFn{Title}

    \resetcounter[footnote]
    Reusing the first regular footnote counter.\footnote{Footnote}

    \stoptext
