If you have a, say, two cloaking devices, one that gives:

Level 2 Active
Level 3 Passive
Level 5 Gravitic
Level 3 racial

and one that gives
Level 4 Active
Level 2 Passive
Level 0 Gravitic
Level 0 racial

("racial" is actually two different techs)

If you have BOTH these devices on your ship, you'll have a combined cloaking ability of:
Level 4 Active
Level 3 Passive
Level 5 Gravitic
Level 3 Racial

And be detected by level 4 active sensors, level 3 passive, level 5 gravitic, and level 3 "racial" (cloak level = or < sensors, detected)

So yes, cloaks can be set to provide differing levels of protection against different kinds of sensors, and they CAN be combined.

EDIT: and in other words, the ship in Q's example question would NOT be visible unless you had a sensor other than tachyon or hyper-optics.
