#4 might be "C.r. Boogie Band - Falling On The Floor" from 1980. But in want of a file i can't prove it
Same song was requested here too with the same guess as mine but also without proof

At least style und era would match

"Song 3" is wanted also here: http://www.watzatsong.com/en/name-that-tune/816.html
