Hi,
First conform to me, you board is single side or double side. if you board is single side you have to take routing in bottom side only.
you trace width should be 12 mil for single side for double side more than 6mil is better.
for Power (+5v) single side 40 mil,double side 20 mil

Hi usha,
i need some clarification in your board from input of image.
1.your board is single side or not ? (if it is single side take trace from bottom only)
suggestion:
trace should not 90 degree,reduce the board size,use trace width minimum 12 mil for normal trace and power better 20 mil or 40 mil depends on amps.
refdes orientation like that only (see image i)

let me know the pad size ?

hi usha,
for single side,better use oblong pad it is will be easy for soldering perpose
