Don't take offense, but it looks to me like an academic homework rather
than a real world problem (and shouldn't you do your homework by yourself?).
Can you give some justification for this kind of text transformation via
SQL?
1 and 3 can be done in a stored procedure or execute block statement,
where you have loops at your disposal and you can traverse a string
character by character, I can't think of a simple query doing that.
2 is an easy one, a simple iif and substring should suffice, e.g.:
select
iif(substring(AFIELD from 1 for 1) in ('0','1'), '-', '+') || AFIELD
