Newbie problems please help asap

Sprouts much taller today, those two straightened all the way out and have grown over an inch today. Guess i did something right lol, no transplant shock at all either, besides the one it died, New seed in germination and its almost ready, can i just use the same pot i had the sprout that died? I mean it wasnt in there long so shouldnt the soil and all be ok.

lol i guess im doing things right then because no ones going whoa hold up change that. lol :-D
