I'll do the first problem. With the other questions you should tell us what difficulties you have to do them.

1. I assume that the basic function reads: $y = \dfrac1x$

Shifting 4 units to the right will yield: $y = \dfrac1{x-4}$

Dilation by the factor 2: $y=\dfrac2{x-4}$

Translation by 5 units upward: $y = \dfrac2{x-4} + 5$
