I'm not familiar with how you actually enter things for LuaTexts tags, but these Lua snippets should get you started, and maybe someone else can explain how to get them into LuaTexts:

Inquisition seconds remaining on player

local _, _, _, _, _, duration, endTime = UnitBuff("player", "Inquisition")
if duration and endTime then
    return format("%d/%d", endTime - GetTime(), duration)
end

Censure stacks on target

local _, _, _, count = UnitDebuff("target", "Censure")
return count or 0

Remove the "or 0" part if you don't want to see a 0 when the target doesn't have Censure.

Shorter name text
I'm not sure what the included name tag is showing that's too long, or what length you consider "too long", but this will return "Name" for same-realm players, or "Name-Server" for cross-realm players, and cap the whole thing at 20 characters.

local name, realm = UnitName(unit)
if realm and strlen(realm) > 0 and realm ~= GetRealmName() then
     name = format("%s-%s", name, realm)
end
return strlen(name) > 20 and strsub(name, 1, 20) or name

This snippet will not do anything by itself, as the pink part ("unit") is a variable that needs to be set/renamed to work with LuaTexts.
