Good definitions of typographical terms, as well as a host of excellent
typographical background and advice can be found in Robert Bringhurt's
_Elements of Typographic Style_.
In Bringhurt's definitions:
Titling figures -- Figures designed to match the uppercase letters in
size and color.
Text figures -- Figures designed to match the lowercase letters in
size and color. Most text figures are ascending
and descending forms.
Lining figures -- Figures of even height. Usually synonymous with
titling figures, but some lining figures are
smaller than uppercase letters.
Hanging figures -- Text figures.
Ranging figures -- [...] Synonymous with lining figures. [...]
Lowercase figures -- Text figures.
Oldstyle figures -- A poor but common synonym for text figures.

No, but then I'm not an expert on typographic history.

In the same way as you use `9' to mean `expertized', i.e. in theory it
is easy and obvious but in practice it may be complex. Let's take a
simple case of Y&Y's LY1 encoding. If a basic font was be, say, ptmr8y,
a superscript version would be ptmr1y and a subscript version would be
In complex cases, one might want to distinguish between a subscript font
with lining figures and one with hanging figures. Similarly, while 1t
would surely mean `superior with some kind of TeX encoding' whether it
would be Cork (akin to 8t) or OT1 (akin to 7t) would be something to
ponder -- OT1 I'd guess with 1d meaning `superscript, Cork encoded, with
hanging figures', 1e meaning `superscript, Cork encoded, with lining
figures' and 1o meaning `superscript, OT1 encoded, with hanging figures'.
Hope this helps,
P.S. My own fonts use my own private encoding, for which I use `p' as
the designator, so my fonts are of the form `pkpr1p1000' (since I need
the design size too).
