This is the second in a series of papers which consider the orbifolds of permutation-type as candidates for new physical string systems at higher central charge. In the first paper, I worked out the extended actions of the twisted sectors of these orbifolds -- which exhibit new permutation-twisted world-sheet gravities and correspondingly extended diffeomorphism groups. In this paper I begin the study of these systems as operator string theories, limiting the discussion for simplicity to the strings with ${\hat c} = 52$ matter (which are those governed by ${\mathbb Z}_2$-twisted permutation gravity). In particular, I present here a construction of the twisted reparametrization ghosts and {\em new twisted BRST systems} of all ${\hat c} = 52$ strings. The twisted BRST systems also imply new {\em extended physical state conditions}, whose analysis for individual ${\hat c} = 52$ strings is deferred to the next paper of the series.
