If you are looking for focus and energy, you always want to look for Sativa strains. They are known as good daytime strains. You can find the same effects with hemp-derived THC products containing mostly Delta 9 THC and/ or Delta 10 THC.

They can, but it depends on a few different things. First, you want to determine what THC compound is in the edible and how much. Taking too much THC, in general, has an intoxicating effect, potentially leading to increased levels of unwanted paranoia and anxiety. So check the levels of THC, and make sure you start small if you are in doubt OR just starting.

If you want an oil that offers levels of added focus, it's suggested you look for oils that have CBG or even Delta 10 in them, as both are known for their energetic properties. Depending on its potency, start with half a dropper, wait an hour, and increase as you see needed.

There is no set rule on how much you should take, as it comes down to your body's chemistry. It's suggested you follow the instructions on the product you get; however, if you are brand new, it's always good to do half of the recommended dose and increase as needed.
