A few Leopard Gecko questions?

1)geckos can only tolerate 20 minutes out of there heated habitat buy sometimes can enjoy a little play 2)not really good food nice habitat and a water dish and he is fine 3)put the heater under his hide and he will be fine 4)once a day should be enough maybe even 2 times a day 5)feed him until he stops eating them usually my gecko would eat around 6 or 7 then he stops eating
