I look forward to my other colleagues saying what they think of this suggestion.
For number 1. Could this be pointer? There is a pointer fish an a pointer sign to an exam? The doubt is, this sign is normally TO an exam room and not IN an exam. Any other suggestions?

The answer to 1 is TELEOST
star sign = LEO
exam = TEST

Well done you, gen2, I would never have got that. It isn't even in my list of fish! How you got that, I will never know!
5 stars for gen2!
