I have no idea how standard notepad's regular expression syntax is,
but this would match embedded style in *nix utilities:

style="[^"]*"

For example, with sed, this will remove all so long as there are no
quotes within the style themselves:

sed 's/style="[^"]*"//' index.html > newindex.html

No. If you wanted to match the 12345 in abc12345def, the regex
could be any of:

abc\(123[0-9]5*\)def
abc\(1234[0-9]*\)def
abc\([0-9]*\)def
[a-z][a-z][a-z]\([0-9]*\)[a-z][a-z][a-z]
[a-z]bc\([0-9]*\)de[a-z]

... and an infinite number of other expressions.
