To number every line, use nl:
nl -ba input
The flag means: use a body numbering style of all lines.
To number only non-blank lines, use:
nl -bt input
nl provides a variety of features for formatting the numbers; by default, it separates the numbers with a tab; for a single space, use -s' '. It also assumes a default column width for the numbers; if you don't want such padding space, use -w 1.
To replace leading characters with sed, see Substituting the first occurrence of a pattern in a line, for all the lines in a file with sed, for example:
sed 's/^*//' input
... where the * has to be escaped because it's a regular expression token meaning zero-or-more of the previous item. While there is no previous item (it's an anchor meaning beginning-of-the-line), it's a better habit to escape it.

AFAIK, the*does not have to be escaped if it's the first character in a regular expression (or occurs straight after the^anchor).

Agreed, @Kusalananda, though I had to test it to be sure -- but I'd rather encourage the habit of escape characters that you don't intend to be special.
