Why not just post them at once instead of posting just 5? Or maybe you want to post just 5.
There is BIP443, but they are not up to 443 in total. You can check the and count them on GitHub:
https://github.com/bitcoin/bipsI think they are not yet more than 190 BIPs in total.
I can post all if i exclude the drafted BIPs, the ones rejected and those withdrawn, leaving only the finalized BIP.
Most of the BIP were not finalized, they all made up the list.
