i) FALSE 
Because there is the infinite number of lines that can be passed through a single point. As shown in the diagram below

ii)  FALSE 
Because only one line can pass through two distinct points. As shown in the diagram below

iii)  TRUE
Because a terminated line can be produced indefinitely on both sides. As shown in the diagram below

iv) TRUE
Because if two circles are equal, then their centre and circumference will coincide and hence, the radii will also be equal. 

v) TRUE
By Euclid’s first axiom things which are equal to the same thing, are equal to one another
