Check engine light problems.

So my check engine light was on for a while now. so i got it checked for the billionth time and got my parts. the codes that came up were for the o2 sensors and MAF but the guy at auto zone said the MAF code could have been tripped from the o2 sensors. SO i replaced my sensors and reset the light by disconnecting the battery over night ( is that the correct way to do it? ). Now after about a day of driving the light comes back on and i go to get it checked again. It comes up with 8 new and completely different codes. I dont know if its some thing i did or something thats just wrong. BUt anywho if you guys could tell me what the codes mean and or if i did something to trip them. truck is 1996 f150 inline 6, 5 speed.
The codes are as follow :
po174
po171
po141
p1151
po420
po155
po135
THANKS GUYS
