\+ is not defined in BRE.
Strict BRE needs [0-9][0-9]* or [0-9]\{1,\} instead of [0-9]\+

Taking the assumption that you want the first field and the last 3 fields with some static text in between, you can use awk to slice in from the end and then strip off the double quotes. $NF is the number of fields, which in awk is equivalent to the last field.

awk '{print $1" example "$(NF - 2)" "$(NF - 1)" "$(NF)}' example.txt | sed 's/\"//g'
10 "Stop abcdee fghi jk lmnz SS -c -i567 -i8a9b"
20 "Stop pqrstu vwxyz SS -c -g123 -g456"
10 example -c -i567 -i8a9b
20 example -c -g123 -g456
