Help me with the basics please.

Hi everyone. I'm trying to make a limit to no limit conversion here and I must admit I'm a little lost. In the first hand I have no reads since the player just sat down. The small raises and bets lead me to a calldown. In the second hand, my opponent seems a little laggish pf but nothing out of the ordinary post flop. He's bet folded the flop a few times in the past so I wasn't sure if I should slowplay or not. Is this a standard turn raise. If so, how much?
