sed -ri ':1;/^repo[12]/,/tag/!b;/tag/!{N;b1};s/^(repo(.).*)latest$/\1newest\2/'

Do not forget about the l command for debugging, which shows what you have in the current buffer. e.g:

sed -nr ':1;/^repo[12]/,/tag/!b;/tag/!{N;b1};l;s/^(repo(.).*)latest$/\1newest\2/' file

repo1:\n  replicaCount: 1\n  image:\n    tag: latest$
repo2:\n  replicaCount: 1\n  image:\n    tag: latest$

Production:

sed -ri '/^repo[12]/!b;:1;/tag/!{N;b1};s/^(repo(.).*)latest$/\1newest\2/' file

sed -ri ':1;/^repo[12]/,/tag/!b;/tag/!{N;b1};s/^(repo(.).*)latest$/\1newest\2/'
